When I hover over the little ad at the top of each thread, it's usually the ebook one. It shows up normally. However, if you hover the cursor over that ad text multiple times very quickly. The small dialog continues to appear and then disappear the ammount of times that you hovered the cursor over the ad text.
I know it's only a small bug, but now I know, it's kinda annoying, and would probably take two minutes to fix.
Just add in somewhere along the
to prevent that from occuring.
