Call was rejected by callee in ASP CreateObject line

[Dev]

May be this forum can help me.I had a perfectly running ActiveX DLL file on my Windows 2003 IE 7 ASP application. The DLL is executed from Server.CreateObject command. Just ater the Microsoft Security Patch push, I started getting 'Automation error Call was rejected by callee' error via browser.The DLL executes and performs all the functions except the last statements in the DLL which are myWorkbook.Close and myPresentation.CloseMy log file keeps track of each process and thats how I could see the DLL is doing all it should except closing the invisible POWERPOINT and EXCEL application that I opened to create the PPT and XLS files on the fly. PPT and XLS files were also successfully saved (on the fly) in a dynamic folder on the server.One of the security patch file was KB950759, which is related to IE7 that modified the way that Internet Explorer handles calls to HTML objects and validates data.Does any one know if this could be a cause, if so please tell me how to workaround this fix. I tried to not to execute the obj.Close in my DLL which worked for the first time and then from 2nd time I got some 'Obj Variable and with block variable not set' error due the the previous files that were still open invisbly in the server.EXPERTS PLEASE HELP
