Not working with PowerToys Mouse Jump.

Hi, is not working with PowerToys Mouse Jump. The cursor stucks in the corner between monitors every time that activate the "jump".

You're right, its "by design" you'll have better luck with "corner crossing" algo but i's not perfect. I may introduce a "far distance" moving exception to prevent that.

Thanks.

I think what maybe happens is Mouse Jump moves the cursor but Little Big Mouse doesn't detect the move, and LBM bases its next move of the cursor on the last-known LBM location, not the actual current mouse location?

The PowerToys Mouse Crosshairs utility had a similar issue when Mouse Jump was first released - when Mouse Jump moved the cursor the Mouse Crosshairs utility didn't move its crosshairs to match - see https://github.com/microsoft/PowerToys/issues/24523 for details.

That was fixed by making PowerToys Mouse Jump call the Win API SendInput function to send a synthetic "mouse move" event which other applications (including Mouse Crosshairs) can detect and - in the case of Mouse Crosshairs it uses the event as a trigger to move the crosshair location.

See these links for the relevant bits of Mouse Jump that move the cursor and send the synthetic mouse move event:

• https://github.com/microsoft/PowerToys/blob/2189e7e1b9009c06f02692d6d4ab4b6d01fdd3bb/src/modules/MouseUtils/MouseJumpUI/Common/Helpers/MouseHelper.cs#L58
• https://github.com/microsoft/PowerToys/blob/2189e7e1b9009c06f02692d6d4ab4b6d01fdd3bb/src/modules/MouseUtils/MouseJumpUI/Common/Helpers/MouseHelper.cs#L104

You might be able to listen for that event in LBM and detect Mouse Jump (or any other external mouse automation software) moving the mouse from that and update its internal "last-known mouse location", which might help when any other external utilities move the mouse as well...
