E.g.
start/tab C:\WINDOWS\system32\notepad.exe
yields a dialog
Invalid descriptor "AttachConsole"
you then have to click on the "X" exit button and then "Terminate now" (or otherwise kill the process) -- therefore you don't notice immediately that the mention of "AttachConsole" is the clue to the problem.
It is of course pointless to start/tab a GUI program; it happened to me while I was playing around with my aliases.
