I converted my mdb from Access 2000 to 2003, and the HTML Help called from the F1 key inside my forms no longer works! To be specific, it works when running the mdb through a full version of Access, but my application is distributed to users as a run-time, and the Help window doesn't open in the run-time environment. Any ideas? Nothing changed regarding the Help File and Help Context ID form properties. The chm file is still available to the app. Thanks in advance for any reply.
