AUI little visual bug

[olivier.corrio at gmail.com]

Hi,
on wxGTK i have a little bug on sample AUI. To reproduce it click on
"WELCOME TO AUI", let mouse down and move to the right then move to the
left. When you move it you can see a blue rectangle to see where it is
supposed to be if you release the mouse. Go to the right and then to
the left in the left panel (and sometimes the blue rectangle is outside
the frame). Tp reproduce it the frame must not be maximised. Sorry not
easy to explain it. It is only a visual bug when you release the mouse
the panel doesn't come outside the frame (i took a picture of it).
Thanks

PS on motif AUI doesn't work very well as well
