I used to have MAC OS 10.13 High Sierra on my computer and my Kensington wireless Expert Mouse worked absolutely fine, but now that I upgraded to Catalina 10.15 I started to have problems with the left click especially, for instance when I click on something, it sometimes holds and drags whatever item I'm selecting instead of being only 1 click. Has anybody had this problem too? and more important, any fixes to this? Thank you!
