I installed the upgrade this morning. Painless. There were a few things I found as I have a Wacom Intuos tablet and like to be able to use both MAC and Windows XP to draw with pressure sensitivity. I downloaded the new driver for the tablet from Wacom. What I found is that as it is a pointing device, I need to unplug the tablet and replug it back in, then pressure sensitivity works. However, then it stops working in MAC. But unplugging it again and using another USB port captures the one port for MAC and the other for Windows, so both work. To get the tablet to work the best, Mouse trails set to short work best and the tablet does all functions as it should. In Parallels 4.0, I could not get MIDI to work on my UNO MidiSport wire which is USB to standard MIDI inputs. I have Cakewalk and MusicTime which I use in Windows, now both work on the UNO Midi adapter in MAC and in Windows. I again find that if I capture one USB port for Windows and one for MAC, I can unplug and replug it in and can use both, not simultaneously but I no longer have to use a different wire into my piano which does wear out the MIDI jacks. So I am very happy. I am happy about the changes to Coherence and how the mouse works is fantastic.
