Display and mouse issues with Mac OS X and Parallels

I have a client that just installed Parallels desktop for Mac version 9 on his MacBook Pro running OS X version 10.7.5.  Since he installed Parallels, he has been having random issues with his display zooming in and zooming out and his mouse not responding properly.  Has anyone had similar issues?

Thanks,
John

John,
I will salute that issue.

I have a 2008 15" MacBookPro, and never had a problem with the display zooming until upgrading to Parallels 9. It seems to happen more in Internet Explorer & Firefox than in Office apps.

I use the trackpad in the laptop instead of a mouse, and so can't comment on that issue.

I called Parallels tech support and they said they did not have any known issues as described above.  They suggested that I uninstall Parallels and see if that will fix the problem.

I have been using Parallels 9 since the day it was provided without these issues.  I would suggest re-installing Parallels Tools, this is the main interface that controls peripheral devices.  I have also recently made the transition to Mavericks without glitch.

We upgraded his memory to 8GBs and so far so good.

The memory upgrade helped but it continues to how intermittent mouse/touchpad issues.
He has invested in a replacement touchpad to see if this is the cause of the problem.

We think it is related to a faulty track pad which is placed over the internal batteries that overhead when plugged into a power adapter for too long.  I will keep you posted on the results.

He is having the track pad replaced.  Another insight is that he is running Lion; Parallels version 9 is built for Mavericks.  He is two versions behind;  I think we have found the problem.  I'll keep you posted.

Turns out it was a faulty track pad.  We replaced the track pad and everything is working fine.  Thanks for the comments.
