OOo Impress portable bug?

Is there a bug of some kind in the Impress part of portable OOo? I can get everything else to work just fine, just not Impress. It tries to open up a new document, then freezes up and gives me a general error message. I'm running this from an iPod, and I've been using OOo on it for the last several weeks with no problems until this point. I will try reinstalling Portable OOo and see what that does, if anything.

Thanks in advance for your responses.
