Can you prevent multiple Rbase sessions?

[MJS]

Hi all!

Some of my clients have users that are "a little" impatient.  If Rbase
does not come up right away, they hit the icon again (and again and
again) which causes multiple sessions of Rbase to be started and
continued.....which is not good for a lot of reasons).  Is there an
elegant way of preventing this?

Tia!
