Well, folks, the whole scenario has changed: my old computer died, reinforcing my growing desire to upgrade. Have purchased a new machine with a fast processor, etc.. I'll pick it up tomorrow and after I get everything set up, will see if I continue to have problems. Fortunately, the old machine's hard drive was intact and the tech was able to recover all my old stuff (99% was previously backed up) and copy it onto DVDs.

Will keep you posted, and thanks for your responses.
