Hi, There is a bug in the commit c8aa725. How to reproduce it: 1. create a frame on the root window; 2. In main mode, click the pointer 1 with[out] MOD-1 on the frame. The related functions are MOUSE-CLICK-TO-FOCUS-AND-MOVE[-WINDOW]; 3. Don't move, don't drag, just click, click more times; 4. The frame is moving! Thanks, Des
