I'm experiencing an inventory delay too... when i click on anything in the inventory panel it takes a second or two to respond, the scroll bar is the same and if I move to another inventory window it takes a few seconds longer. I tried clearing the settings file and this worked for a short time.... Now the delay is back and seems to be getting worse... It is very annoying as a vendor ad creator I need to be able to select and change outfits as quick as possible.... I hope there will be a permanent fix to resolve this soon.
