convert_coord & overplotting across multiple widget draw windows [message #82669]

I have 2 widget draw windows and I want to click and highlight in one and plot something in the other. I've managed to get the mouse coords to convert properly upon switching back and forth between windows, but when I overplot lines for highlighting, the lines, after the first call, either become shifted or do not plot at all. So something is still not quite right with the window coord system.

I've set the 1 window to be the active one and I load in that window's !x, and !y so I'm not sure what else I need to do to get it to consistently overplot.

My code is something like

(*pState).wDrawFlux:begin
widget_control, (*pState).wDrawFlux, get_value=value, get_uvalue=uvalue
case event.type of
;button press
0:begin
;left mouse button press
if event.press eq 1 then begin
print, 'left mouse button pressed!'
wset, value
!x=(*pState).fluxd.x
!y=(*pState).fluxd.y
dataxy = convert_coord(event.x, event.y, /device, /to_data)
fiberid = floor(dataxy[1])
print, 'Fiber id: '+strtrim(fiberid,2)

;highlight
oplot, [-5000,5000], fltarr(2)+fiberid, color=!red
oplot, [-5000,5000], fltarr(2)+fiberid+1, color=!red

;plot in other window
widget_control, (*pState).wDrawSpec, get_value=specwin
wset, specwin
plot, flat[*,fiberid]

dot dot dot

Thanks for any help.
