Reposting - I received no responses the first time. I still need help!

I have a problem with a locked worksheet. If I doubleclick on a linked cell
it tells me Sorry, the sheet is protected yadda yadda... but then it opens
the linked workbook no matter whether the EDIT DIRECTLY IN CELL is checked or
unchecked. But this only happens if the sheet is locked - doesn't launch it
if the sheet is unlocked. I don't want this linked file to ever open like
this. How do I disable this doubleclick?

thanks
