[Wine] Smoothly alt+cursoring in and out of fullscreen wine games

[laeg]

I've had CS:S installed before and there wasn't a problem. 

Basically I want to be able to alt+cursor left and right out of Counter Strike: Source to my other workspaces in Ubuntu 9.10, and when I alt+cursor back to the workspace running CS:S let it still in full screen mode. 

At the moment the game follows me to the new workspace minimized, and I have to manually click on it in my lower panel to refullscreen after rightclicking it back to the correct workspace.

I already have the following checked in the graphics tab for hl2.exe:

Allow DirectX apps to stop the mouse leaving their window
Allow the window manager to decorate the windows
Allow the window manager to control the windows
Emulate a virtual desktop 1280x1024 (monitor optimal and the same as CS:S' configuration)

I've tired different combinations of the options but it only seemed to make things worse, the same settings are configured for Eve Online and I can alt-cursor out no problem, and as I've already said there was no problem on my previous install of CS:S.
