Daf,
What type of bugs? Vr 7 to me is very stable, I have it installed in 4 different win7 environments on 2 Asus buildups and 2 macbookpros running bootcamp. I am not a tethered user, so if that is the problem then I can't help much.
DT for me has always been responsive, as was CI before. Both are good points of reference for help on this software as are the training videos.
I found 7 to be much more stable than 6 and was a big user of 6.
I am using it across my product line, Phase One, Canon, Nikon Sony and now Fuji.
I tend to contact my dealer first on serious issues with Phase One as their forum/problem tickets can be a bit confusing to me. I also prefer to talk to someone in person, not over a web contact.
I will also say that if you are win7 user then can possibly cause some issues since both the dealers I have worked with in the past are 100% Mac and I view that as a bit of an oversight. But I guess they base it on their install base.
One thing for sure, if you are having bugs, then you need to totally uninstall all past versions 6, 5, 4 etc. The Capture One cache files (I use session only) will still open with 7.
When I first installed 7 I did have some issues/bugs, after I totally uninstalled all past versions, I was fine.
