If he could disable the right mouse button in Win98, then he had mouse
software installed, as it is not built in.
See what mouse software he had (MS Intellipoint or Logitech mouseware
perhaps?) and install similar.

I would appreciate any tips. My father has a disability and often accidently
hits the right mouse button. Apparently in Windows 98 he was able to
specifically disable the right button with out affecting the left button. He
as upgraded to Windows XP but apparently the option to disable only the right
mouse button is no longer available. Does anyone know if there is a
difference in these options between Windows 98 and Windows XP?

Thanks.
