I am using the latest 9.02 release candidate but I think this is occurring in 9.01 too. This question has been asked before but never answered. I personally consider this a bug unless there is some method to dismiss the popup for good. I observe the problem when I have a method call with a bad parameter list after changing the source method signature. As I move my mouse to highlight the bad code and replace it, Intellij pops up a yellow dialog that covers the source restricting me from hightlighting the code. It's very annoying and a productivity killer when making lots of refactorings. The only solution is resorting to the keyboard and stop using the mouse. Is there a workaround, possibly a keyboard shortcut to dismiss the dialog. I don't want to disable the error reporting, just the annoying dialog that won't disappear on its own. Thanks.
