Internet Explorer 7 and PDF's

I just upgrade to IE7 and now I can't open pdf's online. I try opening a pdf and it says that There is a problem with Adobe Acrobat/Reader. Please exit Adobe Acrobat/Reader and try again. And then when I click Okay it starts loading and then says Windows cannot access the specified device, path, or file. You may not have appropriate permissions to access the item.

Anybody else run across this?

 

nope but you might try reinstalling Adobe Acrobat Reader.
