Using ESS in interactive mode on a x64 Vista platform with UAC turned off, been extremely satisfied the whole time, but now, with the 3.0.684.0 version strange things beginning to happened. 1. ESS suddenly started to block my VPN connection (to work) and this without any deny/allow option message appearing on screen. It just blocks it, never did that before without my consent. 2. ESS all of a sudden starts to download and install new program components without asking for my permission, as stated in the setup. 3. ESS blocks Windows Update without asking for permission to connect, never done that before. A major decrease in functionality, i would say. I think my solution must be to uninstall, download and install it again to try and fix it, but just wanted to investigate if others have had similar problems and if there might be another solution besides uninstall/install it again. Not even sure that will help though.... EDIT: Forgot to mention, i´ve tried the above with firewall disabled, works just great.
