Pro Tip: Fixing a Disappearing Interface in FastSM for Windows

by

FastSM is a popular accessible client for Bluesky and Mastodon, and for the most part it works beautifully with screen readers like JAWS and NVDA. However, some users have encountered a frustrating issue: shortly after FastSM starts, performing any action — such as trying to create a new post — causes the entire user interface to vanish. When this happens, the app is still running in the background but is completely unresponsive, and the usual fix of pressing Control+Windows+W does not bring it back. The only way out seems to be manually ending the FastSM process in Task Manager.

If this has happened to you, don’t worry. There are three solutions below, starting with the simplest and working up to a more thorough reset. Try them in order and stop as soon as one works.

Solution 1: Restore the Window with a Keyboard Shortcut

Before trying anything else, press Control+Windows+W. This shortcut is designed to restore FastSM’s standard visible interface if it has been accidentally hidden. If this brings your interface back, you’re done! If it doesn’t work, move on to Solution 2.

Solution 2: Turn Off the Invisible Interface in Settings

FastSM has a feature called the Invisible Interface, which, if accidentally enabled, can cause the window to disappear when you interact with the app. Here’s how to check and disable it:

  1. Start FastSM and, before doing anything else, press Control+Comma to open Global Options.
  2. Press Control+Tab five times to navigate to the Invisible Interface tab.
  3. Listen for whether “Enable Invisible Interface” is announced as checked. If it is checked, press Spacebar to uncheck it.
  4. Press Enter to save your changes and close the dialog.

FastSM should now behave normally. If the problem persists, Solution 3 below will give you a fresh start.

Solution 3: Reset FastSM by Removing Its Settings Folder

This is the most thorough fix. It completely removes FastSM’s stored settings so that the app starts fresh, just as it did the first time you installed it. Important: after completing these steps, you will need to sign back into all of your Bluesky and Mastodon accounts. If you are not sure whether you have administrator access to your computer, please ask your IT department or another trusted person for help before proceeding.

These steps have been tested on Windows 11 Workstation (version 25H2) with the latest versions of both JAWS and NVDA as of April 2026.

Step 1: Close FastSM Using Task Manager

  1. Press Control+Shift+Escape to open Task Manager.
  2. Press F repeatedly until you hear something like “FastSM collapsed level 1.”
  3. Press Alt+E to end the FastSM process.
  4. Press Alt+F4 to close Task Manager.

Step 2: Open Your Home Folder in File Explorer

  1. Press Windows+R to open the Run dialog.
  2. Type a single period (.) and press Enter. This opens your personal home folder in File Explorer.

Step 3: Show Hidden Files and Folders

  1. Press Alt by itself to focus the File Explorer ribbon.
  2. Press Right Arrow until you hear “View button collapsed” and press Enter to open the menu.
  3. Press Up Arrow until you hear “Show collapsed,” then press Enter to open the submenu.
  4. Press Up Arrow until you hear “Hidden Items.”
  5. If “Hidden Items” is not announced as checked, press Spacebar to enable it. If it is already checked, press Escape to leave this menu without making changes.

Step 4: Switch to Details View for Easier Navigation

  1. Press Alt by itself, then press Right Arrow five times, then press Enter to reopen the View menu.
  2. Press Down Arrow until you hear “Details,” then press Enter. Note: even if “checked” is announced, pressing Enter here will not change anything — it simply confirms the Details view.

Step 5: Navigate to and Delete the FastSM Settings Folder

  1. In the file list, press Down Arrow until you hear “AppData,” then press Enter to open it.
  2. Press Down Arrow until you hear “Roaming,” then press Enter to open it.
  3. Press Down Arrow until you hear “FastSM,” then press Delete to remove the folder.
  4. If a dialog appears asking for permission, press Tab until you hear “Continue” or “Yes,” then press Enter to confirm.

Step 6: Restart FastSM and Sign Back In

  1. Press Windows+D to go to the desktop.
  2. Press F until you hear “FastSM,” then press Enter to launch the app.
  3. FastSM will start as if it has been installed for the first time. Sign back into your Bluesky and Mastodon accounts as you did during the original setup.

Wrapping Up

A disappearing interface can be alarming, but as you’ve seen, there are reliable ways to get FastSM back on track without losing access to your social feeds for long. In most cases, the quick keyboard shortcut or a single settings change in Global Options will solve the problem in under a minute. The full reset, while a bit more involved, is a dependable last resort that leaves you with a clean, working installation.

FastSM continues to be one of the most screen-reader-friendly ways to enjoy Bluesky and Mastodon on Windows, and hopefully this guide helps you spend less time troubleshooting and more time connecting with your communities.
