I am writing to report a recurring issue where a modifier key (specifically Right Alt / AltGr) becomes virtually "stuck" in a pressed state, but only when the AutoControl process is running.

Detailed Description:

Certain applications on my system seem to improperly handle keyboard events. For example, after closing a specific window in the media player "SimpleTV", the application fails to send a "key up" event for the Alt key.

Without AutoControl running: The operating system seems to handle this error gracefully, and my keyboard functions normally.

With AutoControl running: AutoControl appears to intercept this faulty "key down" state and holds onto it, causing the Alt key to remain active system-wide. This prevents me from typing special characters correctly (e.g., in the Polish layout, trying to type Alt+C for "ć" results in a different symbol, like ♣).

Key Findings:

This problem is100% dependent on AutoControl being active. If I terminate theAutoCtrl_*.exeprocess, the issue immediately disappears.

While I have identified SimpleTV as a reliable trigger, this issue also occurs intermittently with other, unidentified applications.

Suggested Solution:

Since this conflict is caused by other poorly-behaved applications, a feature like an Application Exclusion List would be a perfect solution. If I could configure AutoControl to completely ignore all keyboard hooks/events coming from a specific process (e.g., simpleTV.exe), it would likely resolve this conflict entirely.
