wine users - Jun 2010 - Smoothly alt+cursoring in and out of fullscreen wine games

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.

I've tried downgrading to 1.2rc-3, 2, 1 and previous versions, and none of
them worked so I'm back to rc5.

Surely there's a fix for this? I know WINE is coded, and I know that's
something I can't do and I can't fix this problem myself right now, but
as it works all but perfectly apart from the small problem of following me
minimized to workspaces I'm tempted to say that it seems like such a simple
thing and surely there must be a fix?

Bump.
