Idle redo shortcut vanished

Question

I have Python versions 3.2, 3.3.2, and 3.3.4, and when using Idle for 3.3.4, my redo shortcut doesn't work properly, but there are no issues with Idle for 3.2 or 3.3.2. In 3.3.4 when I try command-shift-z (I'm using Mac-Lion), I get undo, instead of redo. However, if I open the Edit menu, and then try command-shift-z, redo works properly. Is there any reason why this would occur, or a solution to this?

Answer 1

This appears to be a bug triggered by use of current versions of the Cocoa Tk 8.5, such as the current ActiveTcl 8.5.15. I've opened an IDLE issue to investigate.
