I'm not sure if this is a problem with Code::Blocks or GTK, but I have a quite frustrating problem.
I'm running nightly build 4303.
The issue is that when you hover your mouse over a function call, it pops up the prototype of that function (I believe this dialog it shows is called a tooltip).
That's all fine and good, the problem is that when I move my mouse away, the dialog stays. I can pop up other windows, and the function prototype will always stay on top. It vanishes when I quit CodeBlocks, I believe.
This is under Linux and using the latest "stable" release of the GTK runtime, so it could be a GTK glitch. Is it though?
I'll keep a watch on this behavior and update if I notice something else.
