I am testing some codes to send email through Mapi32.dll. The MAPISendMailW calls default email app to popup a draft window filled with address, subject, body and attachments. But after popup, in 5 sec, the popup and outlook app freezes. I have to press once combined key ALT + Tab, then popup draft window regains focus. Have anyone got the same issue? (outlook 2003, outlook 2016, both are 32 bits on 64 bits Win10).
