Hi. Thanks for your response. This was strange problem in that I have been using LabVIEW for months on my machine w/o this issue arising. I think what might have happened is that my last update of virus definitions might have done something (Norton Antivirus) as the problem started right after that.
I did re-install LabVIEW but to no avail. What did work was giving myself administrative priveleges on the computer. I'd rather not run it that way. I would like to keep my regular account free of administrative power as the kids sometimes jump on there. So, it is working now, but if you have any other thoughts to let me return to my previous settings, I'd appreciate it. Thanks.
