First off, I'll say that it is difficult to separate a double-click and a
single-click.  A double-click *always* generates a single-click first.

In C / C++ code, one way to handle this is to start a short timer on a
single-click.  If the double-click happens before the timer goes off you
handle it as a double-click.  If the timer goes off before a double-click
event, you handle it as a single-click.  This is further complicated by the
fact that the user can adjust the double-click time.  So, you first need to
query the system setting for the user's double-click setting.

In theory you could translate this to ooRexx, but I've never tried to do
it.  The delay introduced by invoking methods in your dialog, may make this
not feasible.  But - I've thought that about other things in ooDialog that
work just fine.  So, the only thing to do would be to try it.

That said, I'm not really sure if that is the cause of whatever problem you
are having.  You've explained it well, but it is still hard for me to
picture exactly what you want to do.

Sure, you can send it to me and I'll take a look at.  Then I might be able
to ask better questions about what you want to do.
