Thanks. I'm running Windows 7 now, so should have no problems. What capabilities does Basic have that Viewer does not?

Pugsy, thanks for the PM!

Can anyone tell me what advantage I would get from using Encore Basic over Encore Viewer? Please PM me with site to download Basic. Thanks!

It usually happens when I'm about to nod off to sleep. The same thing happened during my sleep study using a different brand of mask.

I am new to CPAP therapy and have noticed a distinctive "thump" from inside my airway just as I begin to exhale. This only happens when CPAP is in use, I'm very relaxed, and breathing through my nose. If I breathe through my mouth it won't happen. No pain involved, just a distraction. Do any of you ...

I do wish you luck, but expect it will all work as advertised. We're starting about the same time as tonight will just be my fourth with the machine. First night was frustrating trying to get comfortable with the full face mask, but it's going much better now. I had no RT but learned a lot from this...
