Can you post a screenshot of what is happening?

Thank you for your post and screenshot.
I am unable to replicate this problem on my iMac running Mac OS X 10.5.8 (or on my MacBook Pro using Mac OS X 10.6.4).
Do you notice what you are doing when the menu starts changing? That is, are you running a script? Are you using a custom menu? Are the additional menu options accessible? Does this only occur with this one database file, or does it happen with all files?
