I am currently using the 30 day trial of avast 5.0 Pro edition and I noticed a little bug when you click the "purchase a license now" button.
At the top of a the window it opens it says the message "Your avast! protection will expire in %EXPIRE% days." (see screenshot)
Also, it would be nice to be able to click the window and have it open the page in your browser so that you may purchase a license (maybe that upgrade window can redirect to the purchase page?) instead of having to manually go to the site and purchase a license. Just more convenient
. As of now it only opens a window and the only options are "I already have a license" and "remind me later"
**EDIT*** If you click the "I already have a license" button,a menu to insert the key opens, but the "remind me later" button does nothing.
