Already a ticket on it and I've actually already got it fixed I just haven't pushed it yet.
On the holy power issue: I have the latest Alpha and HP still doesn't work right for me - at least I can not reposition the power indicator in any way - I can't even inactivate it. (Although I could turn the module off ;-) )
It appears that the layer ordering has changed in some way that affects some, but not all users. (I am running wow on Linux/wine - maybe a factor.) The workaround/fix for arkinventory is to add the frameStrata and toplevel tags to the item frame:
Line 442 of ArkInventory?.xml:
<Frame name="$parentContainer" inherits="ARVINVFrameStandard" frameStrata="HIGH" toplevel="true" id="0">
Tried this fix, does not work for me. The problem is not with all items in an open bank, and is seemingly random. For offline bank, no mouseovers at all.
