Yes, I've got Dos. It was the first software I bought. When I saw a mate using it I thought I'd never get on with it, but it's beautiful and so easy and direct. I've got the Updata version as well but I kept crashing and losing everthing so I took it off. No more crashes! Updata only support their own feed...be careful everyone. When they announced their latest build I asked if they'd fixed the lost data problem and they removed my post and locked the subject, so I presume it was a NO. 😆
I'm running Tenfore Sat which has it's own charts as well.
Cheers
