--- Comment #19 from caulier.gil...@gmail.com --- I think the problem with button from dialog in TWAIN interface is due to a wrong re-route of TWAIN event loop to Qt5. This last one work fine with Qt4, but with Qt5, this require certainly more indeed tunes. Perhpas a post to Qt community wiki can help.
