Double post back problem with two clicks on a control

Hi,

We are working on a .NET application (ASP.NET/VB.NET). In our application, when the user clicks on a control (say a link, button, check box or whatever) and then clicks on the same control again (while the first click is being processed), the application is hanging and giving errors. This is becuase double post back happens.

Is there a way to avoid this problem. Help appreciated.

Thanks in advance
