Why in the hell do I need to reboot Windows after upgrading Adobe Acrobat Reader? Going from .5 to .7 to .8 required three reboots. Plus they wanted to jam some photo album in there as well.
Your program reads .PDF files. I want to read a .PDF either the file association or mime type will start the appropriate reader. What is being loaded that cannot be uploaded to upgrade? If I'm not viewing a .PDF then there should be nothing on my system pertaining to a damned .PDF.
