A new glitch (?).  AutoCAD LT for Mac; in paperspace, trying to rename a layout is not working.  I select the tab, right click, select rename, and it won't let me put one in.  I've also tried by typing the 'layout' command, selecting rename, and the same result (except then it says the new name I'm asking for is not available).

Anyone else experiencing this?  Advice on how to fix?  Goodness knows, we've all renamed layouts before...nothing too complicated.

Thanks,
