WinMerge displays a modal dialogue every time I edit in my IDE the currently compared file. I'd say this started happening after upgrading from 2.14 to to 2.16 though I may be wrong about that. Is there a way to disable this? The "Automatic rescan" setting does not seem to have anything to do with this (I believe it just refers to changes made within WinMerge).
BTW, I'm really impressed by the changes brought by WinMerge/2.16, kudos for keeping the project alive.
