To be honest, what I usually do in that situation is subclass a widget from Fl_Box, that I set to have NO boxtype and no content (so is "invisible") and then in its handle method I arrange for it to pass on all events except the DnD ones... I then place this "over" the entire main window, and over all the other widgets, and it handles all the drop events for everything. Other events pass through normally. That appears to work and should alleviate the symptom you describe. I'm not at all sure why I do it this way, it seems to be a pattern of some antiquity, so it may date back to a time when DnD didn't work so well and this was the only way?
