Steps to reproduce:
- Start UE4.
- Create a simple Blueprint, connected to the “Event Tick” node (Note: The issue doesn’t reproduce using the “Event BeginPlay” node).
- Right click any of the nodes along the path that have execution pins, and choose “Toggle breakpoint (F9)” or “Add breakpoint”.
- Return to the scene viewport tab.
- Press the Play button.
- Try to click any of the buttons on the main toolbar (e.g. “Find Node”, “Step Into”, “Stop”, etc).
The user’s mouse cursor gets trapped within the confines of the blueprint window (albeit with a thicker, invisible border at the bottom). Please see the attached video: [link]
The user can’t even reach the “Stop” button at the top. Note: The user can exit by pressing the Escape key on the keyboard or Shift+F1.
Same as when connecting it to the “Event BeginPlay” node, the mouse cursor should not be constrained.
