Different mouse types have different driver requirements, e.g. the Microsoft
wheel mouse (Intellimouse Explorer 3) that I use has only two driver
components
C:\\WINDOWS\system32\DRIVERS\mouclass.sys
C:\\WINDOWS\system32\DRIVERS\i8042prt.sys
(the first is the mouse driver, the second the PS2 port driver for the
mouse).
To what extent your Dell mouse is compatible with Word 2007 I cannot say.
One thing to try - some users have reported mouse related problems
attributable to minor corruption in the Word data key in the registry that
have been fixed by renaming of deleting that key.i.e.
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Data
It can do no harm to try it.
