I am using:
_mffind2(searchString, 'I', '+t <Project>', '*.*', MFFIND_THREADED | MFFIND_GLOBAL);
In SlickEdit 10.0.0.3, this finds everything as expected, but in versions 11.0.2.0 and 12.0.3.0, after each result is found a pop-up appears with options 'yes, no, next file, global'
I thought the MFFIND_GLOBAL flag would prevent that, and find all results automatically, without any user interaction.
