Fixed setting expand problem.

Update issue 746
RIDE still messed up UI after resize when settings were expanded.
We spent hours trying to debug this problem before I found "magic"
styles `wx.CP_DEFAULT_STYLE|wx.CP_NO_TLW_RESIZE` from the wxPython demo.
Interestingly using only the latter style was enough to fix the problem
but messed up UI otherwise. This combination seems to work OK at least
on Windows XP. Need to test on Windows 7 and Linux.
