Action! not recognizing OpenGL game

[Patrick]

Hello, I recently purchased Action to record gameplay on Minecraft (minecraft.net) but the recorder is not recognizing it as a game... It was actually recognizing it yesterday when I recorded, but today it's not working. When I select the "Games and applications" recording mode, the record button is blanked out and unclickable. I'm trying to use the MP4 format, if that helps... Please provide a fix, thanks!

Recording button is always grayed out in Game/Application mode. You have to be actually in game or application to start recording. You can start your video recording with F9 hotkey.
