[MacOS] Cursor location issue with wired mouse

[Turbokees]

Heya. 

 

I've got a 2010 iMac running high sierra, with the original magic mouse and keyboard which work without any issues. 

However, when using a wired mouse (an old Mad Catz rat 7), MacOS seems to only update the cursor location whenever any of the mouse buttons are pressed. 

 

The position of the cursor will be visually updated when moving the mouse around, but (for example) any clickable links under the cursor will not be highlighted unless the position is (for lack of better words) manually updated. 

This includes the detection of the cursor down at the dock, causing it not to pop up when I move the cursor near it (unless I click/drag down to the dock, then it will register the cursor's position there).

 

The issue seems to persist when I connect both the magic mouse and wired mouse at the same time, and it disappears whenever I disconnect the wired mouse.

 

Has anyone else had this problem before? Is there an (easy) fix for it?
