Comment 8 for bug 434502

When clicking by TS/VNC, those Motion_Notify events call on_motion() handler in nl-icon-tile.c, which emits "begin-drag-move" signal if LMB is down. Maybe the easiest (and maybe the dirtiest) solution is to check if motion is happening at the same point (or near) where LMB was pressed. Attached file is an illustration of this idea (not a quality patch, i am not a coder). At least, now i can launch any app in any category with touchscreen (and still can drag it to Favourites).
