I installed 3.0 4124 and upgraded my VM's without a problem. However, once I installed Parallels Tool on Centos 4 and rebooted, I ended up with 800x600 as being the only screen resolution. I had to hand modify xorg.conf to get 1440x900 back. It seems that installing Parallels Tools for Linux modifies xorg.conf (possibly among other things). I do have a custom screen resolution of 1440x900 enabled in my virtual machine configuration, but it seems that Parallels Tools for Linux ignores this. This is clearly some sort of bug. After fixing 4124 and running a while, I upgraded to 4128 without a problem. But when I installed 4128 Parallels Tools, the same thing happened. So it is not fixed in that release. BTW, 4124 Parallels Tools seemed to work fine with 4128.
