How old are the older versions?  If they are older than 7.6, I'd expect problems with our enhancements. Especially Flash Redirection on sites like Youtube and many others.  If it is the default 7.6 Connector this would probably work ok for now. 
Hello  I've just seen the update and have a couple of questions if anyone can help please.  1) Does this allow Windows 8 to use Vworkspace or just Windows 7 with RDP 8 update? 2) When is the new version due out, I'm trying to work out if I should do the hotfix (some users have Windows 8) or wait for the full release. 3) If I update will users running an older version of the connector still work?  Or do I need to organise updating everyone.  thanks  Ian
