gcc version 5.1.0 (tdm-1) on Windows XP sp3, 32 bits
I will try to duplicate the issue later today on Windows 7 using gcc version 5.1.0 (tdm-1) .
And, post a patch that I will test on Debian Linux; IIRC, wxSmithAui is both an Windows and Linux project; so the changes need tested on both.
Currently doing Linux stuff; so, will have to finish that before re-booting to Windows 7.
