Scrolling with Assets + closing the panel (Perch 2.5)

I've been having some problems with Assets after uploading enough to have to scroll through them.

I am using Chrome on Windows 7 64bit and have tried in IE and Firefox with similar results.

I either see:

two sets of scrollbars - have to scroll sideways to see the thin scrollbar, then use that to scroll through the assets

no scrollbar (can't scroll)

no scrollbar and images cut off (if using smaller window then making the window fullscreen)

Closing the Assets Panel

When you open Assets from a content region the sidebar toggles to the small view with "Log out" becoming a cross. I was confused at first as it looks a lot like you hit that cross to close the Assets panel. Might be troublesome for clients using Perch.
