webBrowser Control resource problem

I am just puzzled regarding this problem in using the webBrowser control since I don't see any reason why this could occur. Anyway, here it goes.

There are times that I receive this exception error:

System.Runtime.InteropServices.COMException (0x800700AA): The requested resource is in use. (Exception from HRESULT: 0x800700AA)

Any help on this matter will be greatly appreciated.

Thank in advance!

Well, without more info is hard to know.. That's ERROR_BUSY usually happens when IE is doing something else, e.g. displaying a window.alert message box.
I haven't looked into a solid answer for you, but make sure the application your webbrowser control is operating in is running in a static thread (this means having the [STATThread] attribute on your Main) and also make sure you are only accessing the webbrowser control from the actual UI thread queue - so if you are multi-threading (or using a timer or anything like that) you will need to use the .Invoke() method to insert your requests into the UI queue.
Best regards
