I recently tried to import and use another Windows guest, where I had strange problems getting the keyboard running. I therefore played a bit with turning mouse pointer integration on and off, but didn't succeed and gave up. Now my problems began: The long time working Windows guest does not accept the Alt and AltGr keys anymore. That is very annoying for me as I need them to get the curly brackets on the German keyboard (I'm C++ programmer, and by the way, Qt contributor ;) ). Like suggested in [1], the following both work: * Pressing Windows+Alt or Windows+AltGr together * Disabling mouse pointer integration But as this had worked perfectly fine before with mouse pointer integration, any chance to get it back?
