Problem with keyboard shortcuts

I am using Scrivener 1.53 and OS X 10.6.1.

Has anyone noticed a bug with the keyboard shortcuts?

For example Command-z and command-shift-z handle Undo and Redo. However, sometimes the Undo command stops working and when I go into the Edit menu I can see the keyboard short cut for Undo and Redo are both registered as command-z.

Redo does reset to command-shift-z after a while or upon a restart but it is a weird bug.

This is a documented bug which, I believe, should be rectified in 10.6.2. See:
