I already explained that I accidentally put
XP window variant 2 as the default in 2.7.1 (I'm very low on time atm so I haven't yet been able to upload a "fixed" release). Just extract variant 1 if you don't like it and you get the old way of displaying XP (which will still be incorrectly rounded). Variant 2 is more exact in a way, but I admit it needs getting used to. Both variants are explained in the changelog for 2.7 btw.
And just continue to /bug the XP rounding until SOE gives us back the unrounded data like it was before.
Ambrosia, I'm not releasing separate windows because I don't have the time to keep them all up to date. You'll need ProfitUI_styles (and have it referenced in eq2ui.xml) and the fonts + the folder images\fonts. If all you want is the open all button, why not just bind it to a key? (I know, just like the bags, some people prefer to click...).
Naruni, I thought I set it up so you can click on the target are instead to target yourself? Also, clicking the health/mana bars in the XP window will target yourself.
EMK, that's happening with all UI's. Usually hitting Enter or "/" or whatever your chat key is should make the windows reappear.
Taffu, I'm not sure what's happening for some of you with the bottom bar, but I explained a couple of (my) posts up how you can edit your uisettings to (hopefully) fix it.
