I can't find the declaration unit of CkMailboxes_Dispose. CkMailboxes_Dispose is used in every Delphi example code in order to free mailboxes.
I have ChilkatActiveX-9.4.1-win32 for delphi.
There is no xxx_Dispose method when using the ActiveX. I notice that the ActiveX examples for Delphi mistakenly include the "_Dispose" line which should've only been included in the examples using the "Delphi DLL" which is not an ActiveX. I'll have the Delphi ActiveX examples re-generated right away..
