I have been experimenting with a cannibalised version of the VFP6.0 'mailbtn' container class (in \samples\vfp98\classes\buttons.vcx) and created a class of my own which automatically sends a subject, message and attachment. I have made sure that it signs the user on and off again each time using the SignOn and SignOff methods.

When placed in a test form it works fine. However, if I close the form and try to run it again it returns an error from the MAPI controller (usually it can't find the attachment). If I quit FoxPro and start it again, the same code works again. Any idea what I'm doing wrong?
