Re: [APML] Combining more than two images in RegiStar

["Bert Katzung" <katzung1@attbi.com>]

Hi Rajiv:
Thanks for this explanation --- it confirms what I sort of blundered into by
trial and error. One of my problems is the number of images open on the
screen after doing a couple of registers and keeping track of  what is
related to what. Getting better acquainted with the Groups Manager should
help with that, I guess. Till now, the Groups Manager has been an enigma to
me.
