It is totally fine to use wxPython 3 on Linux, so the solution is to fix
the bugs. We actually need someone testing it with the newer version. Most
bugs are quite easy to fix, so please report them to me directly offlist
and I will let you know if I can fix it immediately or if you should create
a ticket in case of more complicated things.

wxPython on Mac is a different story, it's much more problematic, because
the 32-bit version is difficult compile with and the 64-bit version is
buggy. No idea about Windows.

I fixed the colorrules.py, could you send me some more info about the other
problem?
