Distinguishing simple and double clicks

[-= JB =-]

Hi Eric,

If you look at the script you might be fooled into thinking
I am checking for a mouseDown but it is the mouseUp I
was checking.

Here is why I wrote it.  I was using the mouseUp and if
a person clicked on some text it would bring up a dialog
displaying the text with the line and item numbers.  Then
i allowed columns to be collapsed by doubleclicking and
if a person double clicked text instead of a mouseUp it
created problems.

So I used the clickFlag to trap for the mouseUp.  Now if
a person double clicks the text it will see it as a mouseUp
and work properly while if they double click white space it
will collapse the column.

As I have said the code looks like I am checking for mouse
downs when in reality even though it is in the mouseDown
handlers it is the mouseUp I was concerned about.
