I tried resizing my window zoom in Firefox on a whim (under View > Zoom > Zoom out) and the script i was running was no longer able to find the 'Submit' button that it was programmed to find. It still tries to push the button at the old location on the screen.

What's weird is that its search criteria has nothing to do with the Relative X,Y coords. I have selected Control Name, TagID, and 'Text' as the search criteria, so it shouldn't be relying on the X,Y coordinates at all.

Does this have something to do with the specifics of Firefox's zoom function?

Has anybody come across this before?
