I have been using v5 on our network of 10 computers with just a 64bit vista desktop as the server with 8gb of ram we installed it around 2/14. overall it has been ok. I like lots of the new updates in v5- but some screens are slow and it can be annoying-

1) trying to document health maintenance or risk factors screens both have a several second pause after you check save on either- do other people experience this- it is annoying but not horrible
2) I use shortkeys a program that will expand a code of say- htn-to hypertension- and longer things that I use in AC- and while it worked fine anywhere in v4 and before certain fields especially the physical exam, assessment and plan areas when i send a command in there it types it out like someone typing 20 words a minute- it happens no where in any other programs and if I open the larger screen for a field with ctrl+e- it works at normal speed there. VERY ANNOYING!!
3) sometimes but not always there is up to a 10-15 second pause waiting to pull up a chart from my message area- this is quite annoying but unpredictable - any one else experiencing this

so if I were you James I would probably hold off not necessarily because of the issues above but for all the little bugs such as shortened fields in the results area- the current version is workable but has some small annoying bugs.
