[MACTCL] ScrollBar Bug in Apple Tcl/Tk...

[Jerry L. <jer...@gm...>]

Grumble...

I can generally cause Apple's Tcl/Tk (Snow Leopard) to crash by hammering the 
down arrow in a scrollbar where several pages of data need to be scrolled...

Here is what I get in the Komodo Console:

I am getting sorta disappointed with the Apple Tcl/Tk system...

Does the ActiveState Tcl/Tk behave mo'better, if so which version would be recommended...
