i know this is stupid but my mouse doesn't seem to operate normaly at all
the left and right click is ok
but the scroll wheel doesn't work
any ideas

Have you check control panel / mouse settings?

How about unplugging and plug it to other usb?

well i try to see the setting but nothing abt the scroll button and several plug/unplug still same
:ashamed:

give it some cheese?

scroll wheel broken. replace mouse.

hey bro i think m not clear enough i mean the scroll is working but ya know how we can click the scroll to perform sliding option actually when i click the scroll the sliding stuff doesn't come out

Just open your mouse, open the button then clean the contacts with a paper sander then put it back.

Be sure to do it carefully. This is the process I am doing when the button was clicking twice or trice even I only click it once.

Good luck.
