System.NullReference Exception !

Hello !

Some times you get an annoying System.NullReference Exception on running any application in VS.NET 2003 even for the first time. Some times this error is caused by some corrupt version of The Machine Debug Manager, Mdm.exe which is provided for program debugging and is integrated into the IE and Windows Shell. So in this case you should turn of Machine Debugger Manager. Follow the following steps to turn it off;

1.	Open Internet Explorer.
2.	On the Tools menu, click Internet Options.
3.	Click the Advanced tab.
4.	Click to select the Disable script debugging check box, and then click OK.
5.	Close Internet Explorer.
	If you run Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me), delete the registry value that starts the Machine Debug Manager. Well I get some of this help from Microsoft.com and hope this works in your case. Best Regards, Haroon
