Problem using iMacros for permalink following upgrade

I upgraded from 2.6.2 to 2.7.1 a couple of days ago and am on the edge of reverting back because I can’t get to update page permalinks using iMacros for firefox. I was able to do this fine in the old version.

Mostly I’ve got my old macros working but on Edit Page (for any particular page), although I can get the permalink edit box open and populated using iMacros I can’t save it.

The click event on the Save button doesn’t do anything unless I physically click with the mouse and the Update Page button doesn’t include the permalink unless the updated permalink has been saved.

(I also can’t automate clicking the edit button for the permalink but clicking the link instead works fine.)

Hoping someone can help before I revert back to what I had working fine a couple of days ago? I’d rather move forward than back though!

Thanks,
Nick
