Unfortunately there is no VMware vSphere Client available for Mac OS X, so I have to run the client in a Parallels 5 VM with Windows 7.
I always get to a point where the client becomes unusable. If I'm working in the console on a VM I can see "Press Ctrl + Alt to release keyboard and mouse" on the bottom of Parallels. If I press it, the mouse gets released, but as soon if I click somewhere it appears again.
In consequence I have to reboot the whole VM and start the client again. Has anybody also seen that issue before?
