hope it’s ok to ask about a renaming query i have here.

i have to export lots of Indesign file files as JPEGS and PDFs. Occasionally i’ll mess up and my PDFs and JPEGs will keep the .indd extension. When i try and rename them by just changing the extension the keyboard locks up while i’m on the desktop. if i go into any software, quark or indesign for example the keyboard works fine but i am unable to go back to the desktop and rename anything until i restart or log off and on again.

It’s really annoying, is there a fix for it.

Sorry it this has been mentioned in here already
