I don't have any acceleration on my computer. As I said I have experienced this problem for a LONG time. Only thing I haven't tried was re-installing Aurora so I will do that next. I've avoided doing that simply because I wasn't if would screw up any settings or make things worse but I'll try that now.
He means going into the Aurora settings and disabling the hardware acceleration option.
When you are "closing out a trainer" are you using the "X" in the top left of the screen before leaving the trainer screen or trying to close Aurora?
