I have the intelli explorer mouse with also PS/2 adapter but i have it sometimes that it hangs but not much.
I have a problem with my keyboard if i hit the F12 button more then twice then the whole system hangs and a restart is neccesary then.And the new version won`t break correctly this version sucks i whas happy because finaly my mouse worked but if it don`t break it is useless.I will install 4.05 again because that version breaks correctly.

ysco.
