I always set my Microsoft mouse to make a "double click" when clicking the wheel button, it's very comfortable. Now, I see IDEA not always opens the file when I click it with with a wheel (thus, meaning the "double click") - most of the times it opens the file but sometimes it does not even after wheel-clicking it a number of times.
A usual double-click works just fine.
Did anybody else notice that ? Should I file a JIRA ?
