Illustrator 2025 Selection Tool Bug

[Giuliano_Fenn]

Hello 
Since the latest update of Illustrator the Selection Tool is not working properly.
After selecting an item on the canvas the cursor becomes a crosshairs and drags the item around with any further mouse movement. The Double Click To Isolate function no longer works because of this and I can't seem to understand how this option can be disabled.
See the video attached.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Are you using Magnet or any other window management app?

This was my issue. I quit Magnet and it works as expected again. Thank you.
