As ever, best to stay up to date - certainly, Nokia Suite on my Windows 7 laptop has never been faster and more trouble-free.
You can get the new version by simply starting Nokia Suite on your Windows PC - if you're already on the beta 'track' then you'll be prompted to download v3.5.14.0.
I asked on Twitter if anyone knew the current non-beta version and received a range of answers - anyone here not on the beta track and know which version the current Nokia Suite download represents?
