Hi
I've been battering my brains for 4 hours now, trying to turn a pixel (any
pixel) on in a DRAW_WIDGET. This is my first attempt at RSI IDL

This is what I have done
-created a dialog box with WIDED, containing a DRAW4 widget, mouse events
enabled, no scroll
-saved the .WID file, created a .PRO file form WIDED's file menu
-changed the default case statement for DRAW events to
BEGIN
PLOTS, event.x, event.y, /NORMAL, COLOR=13
print, event.x, ' ', event.y
-compiled the PRO file from IDL
-ran the applet

The cursor positions (event.x,y) are printed, but no plotting is done

Can anyone help me?
