This info is not the least bit helpful. I use my own modded interface, a modified SARS. However, I went into game and loaded both FreqHTW and Frequency_Latest, and did some testing.
1) I have no idea what gauges you mean. The code for filling the gauges is the same in both interfaces, and the values looked fine to me.
2) AA exp: In both interfaces, MQ variables are used. For example, to display AA exp, it uses <TooltipReference>${Me.PctAAExp}</TooltipReference>
. In game, if AA exp % is not working for you, then try /echo ${Me.PctAAExp}, and if that is incorrect (it should be, if the UI one is), then you got a problem with your CHARINFO struct, and probably shouldn't be playing with it on your own.
3) The pet SIT/STAND, with no pet up, is *supposed* to look that way. Please don't go around shouting BUG when you don't know if it IS one. If you were to load up the MQUI_PetInfoWindow.xml, you would see the following comment: <!-- The stand button will ignore its own size/location and always be under the sit button (for smooth toggling) -->
If you have issues/concerns, by all means post them, but try to be concise with what you're seeing. Include basic info, like playing windows/fullscreen, what resolution/color depth, if you're using the UI provided AS IS, or made your own mods, and of course, a clear and concise description of the problem you are experiencing.
Make sure none of the .tga files have been overwritten by another "UI part" that you may have added. For example, you might think you were just making a compass mod, but will find out overwritting the .tga that comes with it, will cause the interface to be fubar'd in places.
