I all my configuration: Windows XP as guest, magic mouse and apple usb mouse. After the last upgrade 7.0.14922 693916 13/09/2011, I have a problem with any of my 2 mouse: when I start Parallels the system (win) starts with no problem but the system doesn't catch my mouse. I can moove the mouse arrow (black one ... the arrow of mac osx) but I can't interact with windows .... Windows is ok .. is not frozen . If I set usb option for mouse to go to the guest side ... the mouse (usb) works on the guest side but not in the mac side ... not good for me ... I need the mouse to booth side. Any Ideas ? tnx p.s. how can I downgrade the paralles version ??? tnx again
