Hi
I'm still getting random crashes when running Counterstrike:Source in windowed mode, however from (limited) trials I've found I'm able to get stable results by launching with the following settings:
-novid -dxlevel 70 -width 1024 -height 768
To put this into your launch sequence, right-click on CS:S in your My Games list (in Steam), choose 'Properties...' and then 'Set Launch Options...' - then simply enter the above into the textbox.
The game will then launch in fullscreen, and thus far has been stable for me, although I'm only basing this on a couple of hours playing without crash, as opposed to the 'somewhere between 5 and 25mins' crash of before.
The only problem with this is the resolution and graphics quality is quite low, however I've not tried tweaking this launch code, say by using -dxlevel 80 instead (which forces CS:S to use DirectX 8.0).
Is there an update in site that will allow me to run in a window, rather than fullscreen? I'm currently running Crossover 6.2.1 on a Mac Pro 2.8 8core with 6GB of RAM.
