I always thought the best way to do dates should be YYYY/MM/DD. That way, a sorted list would always be in correct chronological order.

Oops, that was a last second untested change and it exposed a second problem. The first problem is that I returned "" from get_function_calltip() instead of nil but then tested for nil. The second problem (and why this happened) was the iterative loop never terminated on a successful match. So it would find the right match, show it, then it would search the next file, receive an empty string and display that and so forth. Here is a fixed version. I also added in debugging code. It's off by default but can be quickly toggled to provide diagnostics in the future. MouseHoverCallTips = EventClass:new(Common) -- If you are experiencing problems with this script then set the following -- variable to true to enable diagnostic messages.

Returning "" when the file didn't open was wrong, too, though.
