Has there been a solution to toddeverett's problem? I'm experiencing the same
thing.

I browse to a page which is not being edited (I've checked server & local
folders for .LCK files) and click edit. It blinks like it's about to work,
creates a local and server .LCK file, but then says I can't edit the page
because I'm already editing it on another computer.

This only happens for one file on our site (unfortunately, the site homepage.)
Is there anything I can look for in the templates that might be triggering
this problem?

Thanks.
