I have the 2" filter wheel, and the drivers have never worked well with win 7. I upgraded to windows 10 on my astro rig and it works better on Win 10 than it did on win 7, 64 bit.
The problem I use to have is that every time I started the computer I would need to wait until it started up then I would need to physically unplug the FW then replug it to get it to work.
With win 10 it starts just fine on start up but normally crashes half way through a session. Not such a big deal as I normally spend an whole session on one spectrum.
Orion's drivers are crap, really crap.
