I don't think this is a problem - the array size returned
by the WINDOW_STATE keyword expands as you go (at least for
me), e.g.:

IDL> device,window_state=w
IDL> help,w
W BYTE = Array(32)
IDL> base=widget_base()
IDL> drw=widget_draw(base,xsize=10,ysize=10)
IDL> widget_control,base,/realize
IDL> device,window_state=ww
IDL> help,ww
WW BYTE = Array(33)

The reason I know is that I once made a system for saving/restoring plot
region states which works OK. It's available as a tiny part of the solarsoft
library (see e.g., http://www.space.lockheed.com/eit/ssw_setup.html)

If you don't want the whole package, the routines are called
pstore.pro, prestore.pro, pconvert.pro, pfind.pro, at
http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/display/

There may be dependencies on other software in the solarsoft/gen tree,
though... at least the following:

../idl/string/trim.pro
../idl/system/get_viewport.pro
../idl/system/setscale.pro
../idl/system/setwindow.pro
