Excellent, such a simple fix, though it is somewhat hidden in Win11, and strangely I have did not set that on the old laptop (I just checked it) – no matter it is working perfectly.
I have tried switching off the touchscreen and unfortunately that immediately work 🙁 as the mouse still ceases to function immediately Spacedesk is connected 🙁
I attach the file when the iPad is connected and Spacedesk is running. I had to do a screen grab because the mouse doesn’t work to let me grab the text as I did above 🙂
