A few things I found...

When I looked at my friends test forum heres what I found..

Admin Tab (Main screen with IPB Update area...

The information bar is missing, the one with the Title and descriptions underneath.

Components Tab

The tab brings up the main page of IPB in a framed window yet the info bar says even if you click on a different title like Company..;

"Invision Gallery Manager
You can set up and manage your gallery in this section."

Tools & Settings...

Why is the "Export Selected Settings" at the very bottom and not in a faux button? Or setup like "Import an XML settings file"?

Also in the left menu columns it is hard to read orange highlighted text over lt. grey...

Look & Feel...

The menu item icon is missing from the Export text...

Also when editing HTML Templates in a framed window...after choosing a template bit, when the right hand window opens up, you have to scroll over to see the IE icon...?

And when searching for a template bit, such as <{A_POLL}> I get an error such as; Could not find template bit called: <{A_POLL}>, I tried just A_POLL and same results, I did notice this on the 2.1.x version as well....

Well thats it for now, I am sure we (customers) will find more. Since this is a beta version after all. Thanks for letting us test it out...
