I have tried multiple times to isntall R Studio in our environment. It loads quickly, but writing q() for instance hangs and hangs for minutes and then quits. Same does tools -> global options drop down. or help -> about r studio
I then allowed R through the firewall and changed my default working directory from ~ to c:\users<username> and that fixed it.
This post is either ment as help to the next person who stumples upon this or as input to some more debugging/testing in the rstudio product itself.
