I'm having trouble viewing pdf files that I download from my browser. I get a "download complete" notification, but when I click on it the notification goes away and nothing opens up. When I go into the "Downloads" app in the app tray all of the files are there, but when I click on them it says the file can't be opened. The only way I can open them is if I go into adobe reader and find the file in there or go into the actual downloads folder via a file manager and open the file from there. Anybody know what the problem might be?
