Then wx.TheClipboard.Flush() may cause a memory leak problem? Is it possible to avoid this? What about Notepad and other applications? Do they all handle clipboard stuff this way?

Hi,
I'm new to wxPython but can't seem to find the answer to this
anywhere. I'm using wxPython2.6 with Python2.3, for Windows.

I am using the glCanvas, but don't understand the constant redrawing.
It seems like onPaint is called constantly, and my scene is always
redrawing even when nothing has changed. I wrote my own draw()
function, and I call it every time I make a change to the scene, but
then the scene doesn't redraw if say, I move the glCanvas out from
under another window. Can someone tell me if there is a way to not
redraw my scene constantly?

Thanks,
tynia

Yes, I think so. Some programs will warn you on shutdown that they have
put a large amount of data on the clipboard and ask if you want to keep
it there. (Paint Shop Pro does this, and I think I've seen others too.)
