I have used Hugin successfully for many years. However, when I tried to use it again recently (after a lng hiatus) I found that the move/drag feature in the fast preview wasn't working. Clicking and dragging in the preview had no effect. I built from the mercurial source code and found the same problem present. Some debugging work allowed me to figure out what is happening. It seems that when I click in the preview, X is sending a MouseLeave and a MouseEnter event before it sends the MouseButton event. Why it should do this escapes me, but it's not a hugin-specific thing because I see the same in xev in two different desktop environments. Here is the xev output I get when depressing a mouse button: LeaveNotify event, serial 40, synthetic NO, window 0x5c00001, root 0x29e, subw 0x0, time 1220586960, (117,73), root:(747,1690), mode NotifyGrab, detail NotifyAncestor, same_screen YES, focus YES, state 256 EnterNotify event, serial 40, synthetic NO, window 0x5c00001, root 0x29e, subw 0x0, time 1220586967, (117,73), root:(747,1690), mode NotifyUngrab, detail NotifyAncestor, same_screen YES, focus YES, state 256 KeymapNotify event, serial 40, synthetic NO, window 0x0, keys: 4294967198 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ButtonPress event, serial 40, synthetic NO, window 0x5c00001, root 0x29e, subw 0x0, time 1220586967, (117,73), root:(747,1690), state 0x0, button 1, same_screen YES Hugin handles the MouseLeave, but not the MouseEnter. It only deems the Mouse to have entered when there is also a MouseMove, which normally would be OK, but doesn't happen here. Thus hugin thinks the mouse is not in the window and ignores the MouseButton event. This can be fixed by properly handling the MouseEnter event. I have done that in the attached patch, which fixes the issue for me.
