| Subject: | Memory leak in Tk::ProgressBar |
The attached script demonstrates a memory leak by using Tk::ProgressBar.
There is no memory leak with the same script and Tk 800.025. The only
change between both versions is the introduction of Tk::Trace, so I
think this is the cause. Probably the easiest fix: revert to the old
code.
