Grizz Town

Hi guys, i need help im playing day z on xbox keyboard and mouse and all of the sudden when i slide my mouse over my inventory it scrolls up an wont stop, its like the scroll wheel is stuck but its not, ive tried 3 mice all do the same ive uninstalled an reinstalled still nothing, if i turn the mouse off an use controller its fine. Only when the mouse is on does it do it and only when the pointer is on the inventory. Any ideas how to fix?
