Description

While editing CSS files, NetBeans tends to freeze. This always happens when popup help appears. For example I start typing "background". But then a popup appears, showing help for "backface-visibility" which is completely irrelevant, and NB hangs for about 20 minutes.

You never know when it would happen. It happens in a minority of cases, but it still means it happens at least once a day.
