In my reading it very clearly confirms the opposite.

The quoted portion from Mark refers to the relatively rare edge case in 
which one might want to process both single- and double-clicks in a control.

In such a case the OS-provided messages are working as designed, LC's 
support of those messages is fine, and any delay has been introduced by 
the scripter attempting a dual interaction mode for a single control.

Thus far we haven't seen anything in this discussion or anyone else's 
direct experience suggesting that the doubleClickInterval has any effect 
on single clicks.

For the reasons I noted in my earlier post, you may want to review your 
libraries for where that's happening.  And since you're reducing the 
doubleClickInterval to a value below what the user expects, you might 
consider removing that dual model altogether and finding a different 
means of delivering the options you're seeking to provide for the user.
