No Iam sorry I have no solution to this but I will show you some trouble
you got if you don't save some system variables

tek_color
window,1,xs=100,ys=200 
plot,findgen(100)

window,2,xs=200,ys=100
plot,findgen(100)

wset,1
oplot,findgen(100),color=4

wset,2
oplot,findgen(100),color=4


oplot on window 1 gives no blue line.

IDL stores always only for the last plot in !x, !y and so on
the parameters which are necessary needed to add some plots later.

We have two useful routines in our library to get out of this trouble.

;+
; NAME:
;       savesysvar
;
; PURPOSE:
;       saves the settings of the !p, !x, !y, !z system
;       variables in a structure

; NAME:
;       restsysvar
;
; PURPOSE:
;       restores the settings of the !p, !x, !y, !z variables
;       from a structure previously saved with savesyvar()
