I have a problem with maintaining connection to my Blackberry Storm with Parallels 5 with my WinXP guest. Although it connects fine, when using Desktop Manager or Loader, it disconnects and even reboots my Blackberry. It doesn't do this with Windows. I am not sure if this is a Parallels or Blackberry problem, but my Windows PC doesn't do this. Also my VMware Fusion WinXP VM doesn't do this, so I think it is some compatibility issue with Parallels. I want to only use Parallels and get rid of Fusion, but I can not due to this issue. My specs: MacBook Pro 3.06ghz/8gb ram/OS X 10.6.2 using 4gb ram setting in Parallels.
