I need some dialog ASSISTance...

Oh where oh where have my dialogs gone. A user here was working and his dialog box for the Rename command vanished. He typed in his REN shortcut and it appeared to execute correctly but nothing appeared. I tried a variety of things but nothing worked. I did a search on the Autodesk forum and I found a message that said to type in the ASSIST command. When the dialog appears, cancel the command. The missing dialogs should appear. Seemed strange, but we gave it a try and ... they were back. Hmmmm. Are you listening Autodesk. Bug. Thanks for listening.
