Hi, I have delphi 7 app that updates every 100ms an excel doc., it works fine, but if the user clicks on the document he is seeing I get an OLE error 800AC472 in the delphi app. If block the document, I can't update, and I can't unblock/block each time because since the update are each 100ms it's very easy for the user to click in the update....

any suggestions??

Thanks!
