window handle error

Hi, In our window based C#.net application, we are getting this "Window Handle Error" in a random manner. Initially we thought it could be a memory issue but sometimes even if there is enough memory, the same error comes. we are unable to track the root of this error. Any input regarding this error is most welcome. Thanks, Madhan
