editing desktop shortcut labels failed

[ammonet]

It's normally easy to change the text labels under the shortcut icons on the XP desktop. For unknown reasons this stopped being possible on my PC - they cannot be edited directly - the usual rename box appears but typing or deleting has no effect - nor can they be edited during creation of the shortcut. Any ideas?

I now see that I cannot edit the field content in any form - for example, loading software, if I try to enter or change company name - neither is possible.
