>One client informs us that frequently when running a report they get a Fatal error (C0000005 error).
>The code that is executing is REPORT FORM..., so nothing special you would think of. It does not happen always, but in some instances it does happen, so it's not an error that you could easily reproduce. It is difficult to find a solution for this, but what could be causes for this to happen?

If a font used in the report is missing from the computer your app will crash on REPORT FORM.
