One of the ways is to get XtraK from Beagle Bros, which will do a screen move
for you. The XtraK program has a windows facility which is easy to install.

Another thing is to do all the moves yourself. Working on a //e or //c in 80
column mode means you still have access to the /RAM virtual disk in ProDOS.

Try the following (I've not tried this so dont blame me if it doesn't work
exactly this way...) :

	/* before saving anything else on /RAM /*

	BSAVE /RAM/SCREEN1,A$2000,L$FFFE /* HiResScreen #1 /*
	BSAVE /RAM/SCREEN2,A$4000,L$FFFE /* HiResScreen #2 /*

	/* You now have to files in your /RAM disk, on the spot
	   where in normal life the Double HiRes second page would be /*

	/* Now move your screens between the normal HiResScreen and the
	   files on the /RAM disk. Since these BSAVE's and BLOAD's are
	   in effect memory moves, they ought to go reasonably fast /*

As I said before, I've never tried this, but I've read an article about these
moves in which this technique was described. As I don't have a copy of the 
aricle with me, I can't give more details.

I hope this helps you out someway or another.
