I purchased Version 3.0 as an upgrade and have Version 4128. Coherence is a mess. I end up with two mice on the screen or no working mice. It is not usable in Coherence which is my main reason for using. I tried the method of removing the Tools and re-installing but it did not work. I would like to downgrade back to Version 2.5 but cannot figure out how. Can you please help me with this....it appears I am not the only user with this problem and no posting has been made to fix this yet. Thank you.
You want to beware of downgrading to version 2 of Parallels Desktop. Your converted version 3.0 virtual machine won't open and run in earlier versions of Parallels -- it's a one-way trip unless you have a backup copy of the the HDD file with the un-converted virtual machine on it. Hope your Coherence issue is addressed soon. Don't have anything on that, although I would try uninstalling Parallels Tools, restarting the VM, and re-installing Parallels Tools. You can kill PT from the "Add or Remove Programs" Control Panel. - - - - - - Late thought: the "Mouse Sync" option could be something to try turning off, first. HTH/swv
