When I highlight a command in the builder window and strike the F1 key the help window does not display. The help file is located under the following path."C:\Program Files (x86)\HPCCSystems\4.0.0\eclide\bin\ECLReference.chm"
It works fine for only one of the 8 people on our team. So there seems to be an issue with the install perhaps. I tried reinstalling and that did not fix said issue.
