Hi, I have a problem with helpfiles in my Delphi application with multiple forms. I specify context sensitive help on each form's helpcontext property, and then in the onclick event of the help button, I assign Application.Helpfile to point to the application's executable path + the helpfile, and set the Application.Helpcontext property. This usually works on most computers - but sometimes on some computers when clicking the help button (or pressing F1) a message comes up saying the file can't be found, and you can select the file then from a file open dialog - the path is then correct so I think it just "forgot" the helpfile's name or something. It makes debugging a nightmare as it always works on my own PC and then occasionally it doesn't on other PCs. Any suggestions?
