Mouse pointer keeps changing on me, annoying!

Anyone know why this mouse pointer is doing this? Restarting the computer and the mouse pointer is the normal single arrow at an angle, even when over clickable buttons and such. After a few hours of computing the mouse pointer will change to the Move pointer, where it has 4 arrows in a cross. Right now the pointer is a normal single angled arrow unless i hover the pointer over a clickable button or hyperlink. Other times the pointer will just stay as the 4 cross arrows regardless of being over a clickable button. I've went into the mouse settings and it shows the pointer as being a single angled arrow. Ideas?? It's annoying cause sometimes i draft in autocad and i need the single angled arrow to be accurate. Thanks!!!

 

Ok now it seems to be only changing to the 4 arrow cross pointer when hovering over text, whether it be in Microsoft Outlook or Mozilla Firefox. It also is changing when hovered over anything clickable in Firefox, but doesn't change when hovered over quicklinks or the File, Edit, View taskbar. When in Outlook reading an email, the arrow is the slanted single everywhere until i hover over any text or links. This is bugging me.

It doesn't seem to be software specific, cause it is the normal arrow over file names in Windows Explorer, but once you move the arrow to the left side of the window (where the blue bar is that has File and Folder Tasks, Other Places, and Details) it changes to the 4 arrow when over the links like "rename this file" and anything clickable over there.

 

Now it is strictly a four arrow cross pointer everywhere. Anyone know why it's doing this? please help. It has to be windows related, cause i've tried different mice to no avail.

 

ah good thinking. I tried changing mice but i'll try uninstalling the hardware from Device Manager and reboot.

 

But there isn't any mouse software installed? The first mouse was a Dell 3 button mouse that comes with practically every Dell computer. The second mouse is a Logitech wireless laser mouse that was just plug-n-play installed.
