Subject: [PATCH] Corrected problem caused by adding a scrollbar to the
 parameters window in the toolkit, which was to the "tkwait" command, which
 waits for a change in state.  What was intended was to wait for a change in
 state to visible only;  once visible, the "tkwait" command should not invoked
 or else the process will block.
