Symptoms
- Cursor moves on desktop but freezes inside one game or app
- Clicks register everywhere except one program
- App requires a restart to recognize the mouse
- Issue only happens in full-screen mode
Likely causes
- CommonApp-specific input settings or focus issueSome apps, especially games, capture mouse input differently and can lose sync with the OS cursor.
- CommonApp running with different permission level (as administrator)An app running as administrator can sometimes ignore input from devices running under standard user context.
- PossibleOutdated or conflicting mouse driver/software specific to that app's needsGames and specialized software sometimes need specific driver versions or settings.
- PossibleApp bug or corrupted installationA buggy update to one app can introduce input issues isolated to it.
- Less commonOverlay software interfering (like screen recorders or game overlays)Background overlay tools can occasionally intercept mouse input.
What to do
- Restart the specific app where the mouse isn't responding, since this resolves many focus-related glitches.
- Check if the app was launched as administrator while other programs weren't; try running it normally instead, or run everything as administrator consistently.
- Alt+Tab out of the app and back in, which can restore lost mouse focus, especially in full-screen games.
- Close background overlay software (Discord overlay, GeForce Experience, screen recorders) and test again.
- Check the app's own settings for mouse sensitivity, raw input, or exclusive mode options that might need adjusting.
- Update the app to its latest version, and separately update your mouse's manufacturer software.
- Reinstall the specific app if the issue persists only there and nowhere else.
Tools and parts
- None
None typically needed
When to call a pro
If the mouse fails in a specific app even after reinstalling it and disabling overlays, contact that app's support team, since it's likely a software bug rather than something fixable on the hardware side.
