There was a new version 5608 posted today. Prior to that, I used an unofficial version, 5604 (posted in another thread) and successfully installed Ubuntu 8.04 on my iMac 2.16 C2D running Leopard (10.5.3), including the Parallels Tools. But I had one problem, same as reported here - right-click and scroll bar on mouse don't work. I could still bring up the contextual menu (right-click) using the cmd key on the right side of my keyboard. Unfortunately, 5608 didn't fix the problem; in fact it wouldn't even let me install Parallels Tools again as it was stopped by Xorg 1.4. So in that way, this is a regression on version 5604, which at least let me install Parallels Tools on my Ubuntu 8.04 virtual machine. (At least it didn't wipe out my previous PT installation - everything is working the same as before). The mouse problem has been reported in several other threads. Is there a fix coming soon for this - even a beta fix we can test?
