Thanks Eric, not just for that suggestion, but also for providing the packages and very clear instructions on pipelight that have got me this far!
I wiped the installation and started over and made sure only wine-pipelight was used, which was the case:
Code:
1002 2458 0.8 0.1 26804 5644 ? Ss 15:58 0:06 /usr/libexec/wine-pipelight/bin/wineserver
silverlight and netflix are working fine, so it seems to be a problem with installing the unity3d web player. A dialog window pops up and says it is configuring under my user's .wine dir and afterwards I can see it was indeed trying to install something in that dir not .wine-pipelight. I've tried searching the web but I've not found a problem like this yet - just reports that unity3d webplayer was working well in linux a few months back.
