'Below you will find a simplified vesion of code that produces an unhandled
exception error 100% of the time.
'
'Code requires a form with buttons named btnRunMe and btnEXit, and a label
named lblMBX (with WordWrap=true).
'
'And Eudora must not be running prior to execution of the code.
'
'I also tried using the appEudora_OnClose event, but that code was NEVER
entered. Implies that CloseEudora is not completing.
'
'Have I encountered a bug?
'Or, did I screw up?
