Methods .Save and .SaveAs throw run-time error '-2147467259 (80004005)'

[Sascha Rasmussen]

I've written an event handler in VBA which catches the
PresentationBeforeSave-event, its purpose is to start my own
SaveAs-dialog. Everything is running well until it hits a .Save- or
..SaveAs-Method thus throwing run-time error '-2147467259 (80004005)'
without firing the PresentationBeforeSave-event once again.

Env: Windows XP Prof + Office 2003

Thanks in advance,
