This has always happened when you plug in the mouse after starting RO. I find it intensely annoying when playing RO on a laptop.
Plug in mouse first. Then start RO.
If RO doesn't see a mouse when it starts, it will handle scroll wheel events incorrectly.
Sorry for slightly necroing this thread,but i have a question as well.
What if you happened to take the usb plug for the mouse out of the port at anytime and you happen to lose the usb plug part for the mouse and you start RO up again and everything is still locking?Like now,you are playing RO without the mouse and only using the touch pad..
No other choice but to buy another mouse,correct?
