Hm, today, when I tried to run RenderTest.exe some error message occured. Unfortunately, I didn't write it down, so I can't tell you the full content of that message, but it was a memory error. Something like "0x004799483c relate to location written in 0x0000000" or similar... This error message occured only once when I tried to run program and for now it didn't show up again. The program still won't launch tough...
EDIT:
It seems that the problem is with this line:
string home = string(getenv("HOME"));
It's in OAL_LoggerObject.cpp. An unhandled exception error.
