Ofcourse this is not desired, my question is what settings i have to adjust to get a normal dialog box.

Any questions or comments about my question are appreciated.

I've seen this many times in my SharePoint site.

We had problems with others browser, we had to explaint our customer, "since it's a Microsoft tool, you'll have to use IE"

Bu that was just part of the problem, seems to be a CSS problem, you'll have to do a script to make the users to use IE 8.

I'm sorry, i know this doesn't help too much, but we have like a year working with SharePoint, and seems a too expensive tool for all the problems it cause, because we also had to deal with the sinchronization of profiles, but that's another story that cost around a month and a lot of money on consulters).
