Firefox - new mini windows can't maximize?

[axelfox]

I'm having trouble with FF 2.0.0.14 and "popup" windows. For instance, when I use the Click N Ship option from USPS, the postage window doesn't open all the way, and I can't maximize the window (maximize button is greyed out). Another problem I have is with my online fax program: I need to upload a file, but popup window doesn't fully open, so I can't click the "upload" button b/c it doesn't show.

However, some other times it works. When I click "New Topic" in this forum, a new, smaller window opens up so that I can post this message. I can also maximize it.

I'm baffled here.

Thanks.
