Just a minor one that doesn't affect playability, feel, etc. Mostly amusing :P
When I first log in, and the Calendar has pending invites, a blue aura shows at the bottom of the minimap. All I have to do is open the minimap buttonbag, the aura will flash several times, then disappear. Kinda amusing really, lol.
I thought it was the Calender because of the number of flashes it does. I do have RecipeRadar installed also but have never seen that button flash before. Eh, no worry either way. I take the blue blip flashing to be like an "ON" switch. If it flashes, then goes out after checking the calendar, all is well :P
