I am a physician who accesses the hospital network by VPN usually using Internet Explorer. One facet of our access is the ability to review electrocardiograms on-line as PDF files. Sometime within the last 6 months, I lost the ability to see these files on-line, getting a 'this page cannot be displayed' error. I finally figured out that this was related to a security update and when I removed it the problem resolved. I recently upgraded my motherboard and, despite clear instructions, my tech friend updated all the Windows security patches for me and I have again lost this ability. I have no idea which patch is responsible. I considered removing all of them but the warnings regarding loss of functionality are pretty impressive and I thought I’d look for a better way. Any advice? – Jon Morris

There was a recent Microsoft patch, Explorer patch Q832894, that effectively disabled Version 5.0 of the Adobe Acrobat Reader (and older??). The solution was to update to Version 6 of Acrobat Reader. You can also lower security restrictions for a particular Web site by changing that site from the Internet zone to the Trusted Zone. (From IE: select Tools, select Internet Options, select Security, select Trusted Sites, select Add site).--Kent Shaw
