XLoadCT in a procedure ????? [message #5291]

Hi.
I have a slight problem with Xloadct. It does not behave well
when used inside a case statement in a procedure. When Xloadct
is in a procedure, the pro naturally waits for xloadct to be
finished before continuing, but when I use Xloadct within a
case statement, the event handler does not seem to wait for
the Xloadct pro to finish.

The relevant part of my code is:

PRO jv_event, event
Widget_control, event.id, GET_Uvalue=eventval
CASE eventval of

'COLOUR':Begin
XLoadCT
TvLCT, r1,g1,b1,/GET
XLoadCT
TvLCT, r2,g2,b2,/GET
Combine_CT ;calls another procedure
END
ENDCASE
END

This works fine if I use LoadCT instead but I really need to
get Xloadct working in this situation.
Thanx .
