I cleared the proxy files , but no help. I can use the method that you suggested, but it would be quicker with the trimmer. Funny, a few months ago I updated the Disk Image loader. From then until today, every time I would open the Disk Image loader, I would get a window that said " Disk Image Loader Driver was updated. The new version will be used after the next restart." I have restarted several times since, but the message continues to display each time it is opened. Then this morning, after the problem with the Trimmer started, I opened the Disk Image loader, and there is no message about the update. I surely do not know if the two are related but it seems odd to me.
I thank you for your reply Sknis. You and others have helped in the past and I hope you can figure out what the problem is this time. I have also tried changing to software through tools/options but to no avail. Thanks again and I will keep checking and hoping. GRM
