Many thanks for the input. Here are the requested pieces of info and results of trying the various suggestions: Wine's Windows version is set to XP. Copying the version of d3dx9_30.dll from Windows to ~/.wine/drive_c/windows/system32 had no effect. (There was already a file of that name there, which I renamed before the copy.) I also tried copying d3dx9_36.dll to the same directory, but similarly without effect. Running in terminal was more helpful and resulted in the following output: fixme:d3d_caps:wined3d_guess_vendor Received unrecognized GL_VENDOR "VIA Technology". Returning VENDOR_WINE. fixme:win:EnumDisplayDevicesW ((null),0,0x32ec40,0x00000000), stub! fixme:d3d_caps:wined3d_guess_vendor Received unrecognized GL_VENDOR "VIA Technology". Returning VENDOR_WINE. fixme:win:EnumDisplayDevicesW ((null),0,0x32ed04,0x00000000), stub! m Files\TmNationsForever\TmForeverLauncher.exe: main/renderbuffer.c:2153: _mesa_reference_renderbuffer: Assertion `oldRb->Magic == 0xaabbccdd' failed. wine: Assertion failed at address 0xb8025430 (thread 0009), starting debugger... >From the above it certainly seems like it could be a display driver problem. Graphics card is reported as: VIA Technologies Inc, KM400/KN400/P4M800 [S3 UniChrome] Rev01. The driver is whatever Ubuntu decided to use when I installed it. I don't know how to find out what it is using. System-> Administration->Hardware Drivers reports that "No proprietry drivers are in use on this system". I found what appears to be a compatible driver on the VIA Technologies website, but installing it is proving to be anything but straightforward. The installation script is currently telling me that it can't find a VIA graphics card. I'll keep pursuing this. Thanks again. Dunc
