Hello,
I am working on an iMac running OS 10.7, TK 8.5.11. I built a simple app
containing a Notebook widget, and with Listboxes and linked tkk.Scrollbars on
each of three tabs. All of the Scrollbars work the first time I manipulate
them, but once the Scrollbar on third tab (the last one created by the script)
is manipulated, the others become unresponsive to mouse clicks (though the
Scrollbars continue to move when the Listboxes are scrolled using the
mouse/trackpad. I first found this issue working with Python 3.2.3 (using
IDLE), but the same thing happens with Python 3.3. The problem was recreated by
someone on the Python Bug Report list using the same system configuration. I
asked someone to try this on a PC (Windows 7, Python 3.2.3, Tkinter 8.5), but
the problem wasn't recreated.
