Mouse Sensitivity Problems ?

Hi! I just updated to the July 22nd update after being away for a month. The first thing I noticed was odd was that the cursor looked like a regular one, and not the Sims specific cursor, if that's clear. I'm not sure if this is a feature in the new update or not. It also had an hourglass symbol next to it, which apparently means "working in background" despite the fact nothing else was open or on at that time, and it only appeared in the Sims. The only thing that really seemed different was the mouse sensitivity in CAS. It was either too slow or too quick and trying to rotate a character would just make them rapidly spin.  When trying to adjust features, they dramatically changed by even the slightest of movements from me. It is really hard to work with and I can't tell if this is all just new stuff. I even changed my mouse sensitivity in my computer settings but it was still the same. With or without mods, script mods, anything, it still does this. 

Please tell me if this is new or something wrong on my part! Thanks
