Play Buttons Randomly Become Non-functional

[JadedDragoon]

For unclear reasons, the play button will occasionally become non-functional. Meaning that I can click the play button for a mod and the play button will "depress" and when I release the play button it will reset its "position" but then nothing happens. FSO is never launched. In the case of custom mods, the launch window listing the packages of the mod doesn't appear. Closing and restarting Knossos fixes the issue temporarily.

I've checked to make sure I don't have an FSO zombie process... though I don't think FSO checks for the presence of an existing process before launching regardless.

Using Knossos 0.14.3 on Windows 10.
