VS 2005 VB.NET : Web Browser Help Needed

[kkc]

Hi guys i am having a window form, within the form, i have 2 part,
the upper part is a datagridview and the lower part is a web browser (control name :wbBroser).

the situation is this:
when i double click a cell on the datagridview, the web browser will display a web page content, which is working fine.

the code to navigate:
wbBroser.Navigate(strURL)

however, when i click close button which is in the web page, it will prompt out a message :
The web page you are viewing is trying to close the window
do you want to close the window?
yes no

after i click the yes, then the web browser become blank again.

However, when i try to double click a cell in datagridview to launch web browser to view other page, it come out the following error.
COMException was unhandle.
Error HRESULT E_FAIL has been returned from a call to a COM Object.


can anyone tell me how to solve this error?
