It is not good but unavoidable in current plugin architecture. The first thing that every method of every interface have to do is to check versions of every interface it got as parameters and upgrade them if necessary. Otherwise new plugins will crash with old engines/applications when use new methods. Upgrading causes allocation of new VMT which (AFAICS) is never released. Upgrading doesn't replace getVersion() address in new VMT which means that even upgraded interface will return old version and will be upgraded again and again on the next call. -- WBR, SD. ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
