Screen not locked after screen saver

[Bajnep]

After coming out of suspend, the active desktop gets displayed with all the open apps, files, etc. Then, after like two seconds, the screen gets faded to black and then is the password prompt displayed.

it's been a while and I applied all the upgrades in the meantime and this keeps getting worse and worse. Left the machine unattended for a while with VMPlayer 4.02 running with WinXP as guest OS. Came back to the machine, both monitors are in standby, so far so good. Moved my mouse and both monitors came on. No password prompt, no nothing. I interacted with the VM for like two minutes and the shut the VM down. Then, the screens started fading to black and THEN the password prompt came up.

yeah, when the screen goes on, the clock displayed isn't the current one, it's one of several hours ago (or whenever I've left it idle).

Ok, so this happens only when VM Player is running with an active VM in the foreground. The Ubuntu screen saver kicks in but after I move my mouse, the screens aren't locked.
