I will be using vSphere Client (4.0.0 Build 208111) to manage some VM's. I will be typing away in the console and then the keystrokes will stop passing through. It doesn't matter which VM I try, no key strokes will pass through. The mouse works fine. Key strokes work fine on any thing local. I have to close the vSphere Client and reopen it to make it work again.
My workstation is running 64 bit Windows 7 OS.
This started when I upgraded our enterprise from 3.5 to vSphere a few weeks ago. I don't have this problem on any other workstation.
