When I navigate to any pdf file on the web, it loads into the browser window and displays the page for about 5 seconds, then disappears into a blank, white screen. It will display again if I refresh, but then disappears again. I've checked with two other people and they are able to view the document just fine. So I'm thinking there is something wrong with my system.
It does this on Firefox 126.96.36.199 and IE 6.0, so reinstalling Firefox probably won't help.
I just ran System File Checker, sfc /scannow, which completed w/o errors.
I've cleare the cache and cookies.
I'm going to run Registry Mechanic and virus scans right now.
What else could be wrong with my system? What do you suggest?
Any other information you need me to reveal?
