Hi,
well for the files. my bug withing Anno 1503 [1] is about the same. glXMakeCurrent seem to be the very first opengl call at that point and then crashes the app. i tried commenting out some things and it still crashed on the first gl.* command. afaik i put a link to the demo in the bug and if there is something to test, dont hestitate to ask.
A +ddraw, +tid trace might be intersting. See if there are any thread changes in the list of the ddraw calls.
I'll remember anno 1503 for testing.
Stefan
