Context Sensitive Help in C#

Question

Hi all...I have been integrating the F1 context sesitive Help in my C# application.I pass a HelpString to the .chm file(set in the HelpNamespace property of associated HelpProvider) .On clicking F1 the help file opens up.But the help file steals focus from the application.Now without minimizing or closing the Help File,I minimize the application-The Help file also minimizes.Now if I maximize the application,the Help File Does not maximize.On clicking F1 again,the Help File does not open up at all!!!It only steals focus from the application window.Doing an Alt + Tab shows the Help File.But the Help File can again be opened again after restarting the application.Can anyone explain this to me?

Thanks & Regards,
Varun.
