--- Comment #20 from Mike Kaganski <mikekagan...@hotmail.com> --- I would say, that this is not a bug. UDFs (user-defined functions) should not operate on things like controllers, active sheets, etc; they are expected to take data, digest it, and output data. Relying on other data not directly mentioned in the formula is basically breaking the assumptions ... so indeed, there might be no controller when the function is executed (and the load time is just one example; the document may also be opened in headless configurations, etc). -- You are receiving this mail because: You are the assignee for the bug.
