Emulated Gamecube Controller Randomly Disconnects

[SchmokingJordan]

Hi!
I am currently having a problem where my emulated gamecube controller seems to randomly disconnect.
The TAS Input window becomes unable to close, and the controls I put in have no effect on the actual emulation window.
I use a keyboard + mouse so emulate the gcn controller.
I am playing Mario Kart Wii in 20% speed to TAS, so I do use savestates.
Any help is extremely appreciated!

I've heard about this problem once or twice before, but I have no idea how to solve it. It never seems to happen when not TASing.
