This works and doesn't work. Apparently, what happens is that as long as the macro is busy (or maybe it's just with functions that take a long time in comparison, like exporting a PDF), the Cancel button I made on the dialog does not get attention. So if I click on it once, usually nothing happens. But if I keep clicking on it, over and over, and I hit it when the interpreter has time to check the status of the button, then it works.
I'm trying to think of a way to get LO to check the button to see if there HAS BEEN an event, as opposed to checking to see if there IS an event, but I'm stumped. So, other than the delay issue, this could work.
