Open with . . . no longer allows me to choose any of my portable apps
I recently have been unable to open documents using the 'open with ...' in the context menu of Windows (XP) and searching to my portable apps (eg pdf with Sumatra). I have not done anything different. This behavior occurs on both my work machine and my home one (where I have administrator rights). It seems to have coincided with the recent windows patches from Microsoft, but I do not know if there is a connection.
