My 95 was working fine until about a week ago when suddenly the 10 key pad stopped working when the num lock key is engaged. when the num lock is not engaged the keys function correctly. When the num lock is engaged the only key that functions is the 5 key which will cause the window that comes up to be that of the left click mouse key. This is the same on a different keyboard. And when I take the keyboards onto another computer they operate fine. So I think the problem is with my computer. Probably some switch in Win 10. Any one have an idea??
