(* Support for the mouse wheel is provided through a separately-running module, MSWheel, that generates a MSH_MOUSEWHEEL message. *)
My understanding from reading the MS knowledge-maze is that MSWheel has been superseeded by a single driver called something like MSMouse32.dll.
I downloaded the latest software for that mouse model (MS), but the installation did *nothing*. It starts and then nothing happens. Black-hole EXE. (I was using the CD driver that came with it before.)
I don't know if that other link is the same thing.
I reloaded a very old driver from the old non-MS mouse, and it so far appears to work, but seems to lock up the machine about twice a day. But I have not verified that because it is hard to know what locks up Winblows.
I will see if the pattern points toward the mouse, and maybe try that other driver link if the old one is too problematic.
BTW, the laptop is ME.
Thanks for the tips guys.
