I'm using the latest release (v.1631) of TextMate under OS X.6.5 and am still experiencing a couple of unexpected problems:

1 - The keyboard shortcut Cmd-Opt-O, which is supposed to toggle between Insert and Overwrite modes, does nothing. I can make that switch by going to the menu -- Edit -> Mode -- and clicking on Overwrite Mode, but this is inconvenient when I need to make that change often. I've looked at Keyboard Shortcuts under System Preferences to see if there are any conflicts, but saw none. Any ideas what the problem might be?

2 - On a muli-page file the PgUp and PgDn keys have weird behavior: instead of scrolling up or down a page at a time, the window jumps all over the place. For example, on a 5-page textfile and starting with the window about 4 pages down, hitting PgUp puts the window at about page 2, hitting PgUp again puts it at page 3, hitting a third time puts it at the start of the file. This makes no sense to me at all. OTOH, clicking on the scroll bar moves the window one page up or down as you would expect. What might be causing this behavior?

Thanks.
