Keyboard capture lost after unlocking computer

[Kurt Harriger]

Using Ubuntu 9.04 host and host key set to the right menu key with grab input on focus enabled.

1) In VM open notepad as active window for use in step 6 2) With VM as active window, normal window (not full screen) 3) Press host key to uncapture keyboard 4) press Ctrl+Alt+L to lock computer 5) Unlock computer 6) start typing - window should be active but input doesn't seem to work 7) click window or host key and start typing

VM fails to recapture input and I often need to switch focus to another application and then switch back before it will recapture keyboard, but strangely keyboard doens't seem to be working properly in host either after step 7 so when I press ctrl+alt+arrow to move from one desktop to another I have to press host key again to ungrab input before switching desktops... Had the same problem with v2.2.
