I notice that fungus AltTab has been added to the database.
I came across this recently as a result of another post.
I tried it and as far as I'm concerned it's a no-no!
When the program is run it does indeed provide an alternative AltTab. If however you exit the program ,on my machine at least, the normal AltTab is inoperable. What is more Windows explorer is screwed up.
The situation was recoverable afeter a reboot. Sorry not for me!
