I too am having a similar problem with the IPAQ 1910 (although I am using iMAME). Games initially run fantastically, but on trying to quit it looks like my hard keys have opened loads of apps, and I end up having to do a system reset.
Is it anything to do with the xscale processor ??? who knows !
Any suggestions would be helpful.
