Thanks for the hint, and the solution also.
The thing is I prefer the LAZY way
I have managed to subclass
wxAuiManager in C::B code itself say:
wxAuiManagerEx and overridden
OnPaint and did the fixes without the need to rebuild wx.
I had to wait hours and hours to build wx, with all the configurations (debug, release, monolithic, static, shared, ...etc). because I have a slow computer.
