I have just loaded up a Parallels 4.0 trial and had a few problems: 1)It wouldn't boot up initially until I manually deleted it and forced it to regenerate the bootcamp file but deleting the old .pvs file. 2)The mouse capture and release is sluggish and requires ctrl+alt . Not seamless as fusion is. 3)The 3D driver has massive glitches even in games listed as fully supported (I tried Commmand and Conquer 3). 4) The mouse can not click on any windows components in coherence mode. With all these faults found in 5 mins is Parallels 4 Fundamentally flawed or could i beat Fusion 2.0 when patched? If so how long do you think that will be?
