Well...someone on Gamedev.net reported me that FARC 0.4.1 doesn't show any window at the start.... and i reproduced the same problem with the 0.4.1. I though at start that was a dommed release, but my working 0.5 .exe did the same thing !
When i runned the exe under the IDE, i seen it blocked at COMCTL32.dll module loading.. ok after a reboot on Win7 all worked perfectly! the 0.4.1 and of course my working copy.
After a rerun under the IDE i seen that the loaded modulesjust after COMCTL32.dll were atiglpxx.dll and atioglpxx.dll.
TADAM !! ooooh suprising ! ATI superb OpenGL drivers strikes again !
Because when i was on Nvidia i never had this kind of bug.
So all is ok on a release side, but i posted some question on an opengl forum to see how to get rid of this annoying, tiring problem...
So i'm sorry if you had this kind of problem too.
Apart that the 0.5 progress as you can see on the SVN and i'm near to implement the construction rules and the production system.
