This one hasn't been resolved in VS 2005. We still have to manually set the dimension of a browser control on a form in the initialization of the form if we have more than one. I wasn't able to simulate that bug if I only have one control. But, as soon as I have more than one, the dimension of the control is changed when the form is being run. So, I have to do this:
Log.Size = New System.Drawing.Size(Log.Size.Width, 255)
LogHTML.Size = New System.Drawing.Size(287, 453)
LogXML.Size = New System.Drawing.Size(281, 453)
