Mouse Without Borders

Steps to reproduce

1. Use Mouse Without Borders between two PCs (PC A with main keyboard/mouse, PC B secondary).
2. Try to move the mouse from PC A to PC B by reaching the configured screen edge.
3. Sometimes the cursor gets stuck on the screen border and does not switch to PC B.
4. If I left-click on the desktop while moving the cursor toward PC B, the switch works.
5. Switching from PC B to PC A using the mouse connected to PC B always works normally.

✔️ Expected Behavior

The mouse should seamlessly move from PC A to PC B when reaching the configured screen edge, without requiring any additional click or interaction.

❌ Actual Behavior

The cursor intermittently gets stuck on the screen edge when moving from PC A to PC B.
To make it switch, I must left-click on the desktop while moving the cursor.

No response

Start with the Mouse Without Borders implementation and use the reproduction steps to investigate edge switching from PC A to PC B. Review the attached PowerToys report for diagnostics; done means the cursor switches reliably at the configured screen edge without requiring a desktop click, while the existing reverse direction remains working.
