Hey Mr_Maniac and WMCoolmon,
You didn't compile wxWidgets with "--enable-unicode", did you?
Because I experienced those errors mentioned by you, but in greater numbers when compiled with unicode support.
Try adding wxT() around the strings and look if it helps.
I made a patch for the polonius.cpp file, but I could only correct it in places without concating two or more strings together.
Hope this helps, because it seems to me, that most if not every wxWidgets application in this forum doesn't like unicode wxWidgets builds.
