Full Screen/alt+enter BUG
 

Whenever I play on a specific character, Katoo, no matter what computer I use, when I try to hit alt+enter to make the program full screen there is an error box that says "() Rest device failed" and the entire program shuts down instantly. Does anyone know what setting on that specific toon might be causing this error?

Nvidia GPU? Because that sounds a lot like a nvidia driver issue that was never fixed.

I have the same problem...I'm running an ATI Radeon HD 5570 1gb ddr3.

It happens to me occasionally on random characters using Titanium client. To avoid it, use "switch to fullscreeen" in the Alt-O options menu instead.

It could be a resolution issue when it tries to go fullscreen as well. I have seen this in the past on Titanium, but it seems to be resolved in the SoD+ clients.
