I noticed today that you cannot add a comment for an Internet Shortcut in the Application Shortcut Folder. (Any comments will then appear as a tool tip.)
I cannot reproduce this behavior. On my test machine the "Internet Shortcut" does not have a "Comment" field. Could you please send a small test project reproducing this behavior so we can take a look?
The comment was actually from a previous version of my installer project, where the shortcut was actually a shortcut to an installed file (which was an internet shortcut in my AppDir) and NOT an Internet shortcut. Somewhere along the line I changed it to an Internet Shortcut and lost the ability to add a comment.
