Four bugs prevented viewports from working like AutoCAD model-space windows: 1. Dead-code double-click block: `!is_down2` was always false because `is_down2 = sel.left_down` is captured while the button is still held (before the selection block clears it). Changed to `is_down` so the double-click handler actually fires. 2. Inverted pan direction: pan_active_viewport used `-=` on the delta returned by screen_delta_to_world, which is the same delta that cam.pan *adds* to its target — causing reversed drag. Changed to `+=`. 3. Zoom not cursor-centered: zoom_active_viewport now accepts an optional paper-space cursor position and adjusts view_target so the model point under the cursor stays fixed (same as cam.zoom_about_point). 4. ESC did not exit MSPACE: CommandEscape now calls ExitViewport when active_viewport is set and no command is running. Also added MS/MSPACE and PSPACE command aliases, and MspaceCommand / PspaceCommand messages so MS auto-enters the first viewport. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
