Hello Ian Teacher ,

It is not clear if this issue has been ongoing or has just suddenly started.

Often, the reason for 'lag/issues scrolling' are out of date drivers (other users of MAC/Parallels) may also be able to offer advice.

I would suggest closing Studio properly and ensuring all drivers are up-to-date.

Hello Steven,

Thanks for your tips.

I followed all those steps but it hasn't changed anything (I wasn't able to update Windows 11, but I'm running a beta version (ARM insider program) on Parallels so that's maybe the reason for the lack of updates at the mo).

In case I don't have the mouse issue with any other apps, including Office. And I have the same jumpy issue if plug in a basic wired mouse with no drivers and if I'm using the trackpad.

This issue has happened right from the start, when I got a Mac running Parallels last week. I never had any issues with the wireless mouse I'm using when I had a PC.

I don't what happened, but the problem is solved. I reinstalled Office and did a couple of reboots of Windows. Thanks for your help!
