Thanks to Mike_Land and cornwell for the links to the workaround that solves my particular problem (no chords, but really nice to have something that works!). HOW TO: Install a Software Application using Compatibility Mode Hope this helps. This gives me full functionality for the software. Anyway, I just installed the Mouseworks 6.2.2 in the Windows 7 RTM using the compatibility mode for Windows XP. I was really down when I found out that Kensington would no longer support it in Windows 7. Does anyone know if there are any hacks, workarounds, etc to get these working properly? Or if there are any plans to provide support natively in Win7 itself? It's not a deal-breaker for me, but would just be nice :-) Thanks, LINC Hi Linc Did you ever get this fixed? I have used the Expert Mouse TB since it was first put on the market and think it's probably the best pointing device ever produced. I tried to be clever and use the Vista drivers for a more recent version, but no dice. Unfortunately Kensington isn't much help with drivers, with support for nothing more recent than XP. The scroll-wheel only works intermittantly and I have no options for customising the buttons (or using the extra buttons at all). Kensington Expert-Mouse trackball (gotta love their naming convention) - Win7 recognises it as a mouse and it does work, but I'd really like to get proper functionality if I can.

got a recently built new machine and only one relatively minor issue.
