Thanks for such a prompt and absolutely accurate response. I downloaded Process Tamer with Firefox and now it works perfectly. This answer also solves another mystery I encountered some time ago. I was trying upgrade a previous version of Omnipage, but the upgrade just would not work. Omnipage insisted that the upgrade be downloaed by Internet Explorer which now I believe just did not fully download the upgrade. Of course the upgrade became unnecessary with the latest version of Omnipage, but I hope that other programs will not limit their downloads to Internet Explorer. Incidentally, changing the default browser to Firefox did not help; Omnipage upgrade would only come up in Internet Explorer.
