[X2go-dev] Windows client hangs after screen saver starts

I'm running X2GoClient 3.0.1-4 on WindowsXP home. If I walk away from my X2Go desktop for an extended period of time, when I stop the Windows screen saver, the X2Go screen is completely white and refuses to close; it must be forcibly closed. I've tried moving the mouse and typing the screensaver password on the remote system but that did not work. If I let Windows go to screen saver and then immediately end the screen saver, I do not have this problem. Killing the process seems to be stopping xming.

Is this a known issue? Where should I be looking for data to troubleshoot? Thanks - John
