Widget draw problems... [message #15182]

Hi all,

windows 95, IDL 5.1.1

I have the following message error on my program, when I destroy a draw
widget and create another in the same base widget (it isn't a top level
base). But this doesn't happen all the times, just when I switch between the
widgets without drawing more than one time to each!

Also Windows�s GDI resources went low when I caused many of these errors. Next
goes some output that I copied to this message:

IDL> .STEP
% Program caused arithmetic error: Floating illegal operand
;self.wdvel contains the ID of the draw widget:
IDL> help, self.wdvel
<Expression> LONG = 273

;The statement that caused the error was:
widget_control, self.WDvel, /DESTROY
;self.WDvel is a draw widget ID.

If you've stepped on this problem, please help me!
