This may be a function of the doubleClickInterval, a global property
inherited from the system (on Mac and Win; om UNIX it's default value is
250) which is the threshold of time between clicks during which the second
click willl trigger a mouseDoubleUp message.

But rather than altering that value, maybe you could add a mouseDoubleUp
message to your object?

Hope that helps....
