Double click not working, misc adminitrivia

Longtime user of the software, I think it's great!

Sometimes, for some reason on some systems, the double click fails to activate the menu where the middle click works fine.  I came across this on a old and well used system with Windows 10, and on a fresh build of Windows 7.  Not sure why, but there isn't much info online about this software, and that also leads me to some administrivia.

The link for support on the DirectFolders website takes you to a different support forum that is no longer active, so you get a 404 page.  It takes you to bugs.codesector.com for several different things.

Has this software been abandoned??? :(:(:(:(:(:(:(:(:(:(:(:(:(:(:(:(:(:(:(
