I saw this already elsewhere and have been using the B for opening all bags (including GHI) workaround, but as of 7.3 I still cannot open the GHI bag only through clicking the GHI icon.

I also seem to be having an issue not being able to click 'NEXT' when trying to make books or multi-page items. I can add new pages just fine, but trying to access them to fill them out does not work. The cursor for where text should be also seems to be misplaced (an issue I'm finding with XRP as well).

The addons I run:

Skada
DBM
Enemy Grid
Elephant
XRP
MogIt
Unlimited Chat Message
Pawn

I may need to update some of the above (for what is ready for 7.3), but if there are any addons that don't play well with GHI, or something else that might be causing my issues, would be great to know how to fix! Thanks!
