I have a vb.net app which includes an excel sheet. I need to detect when a
cell has been clicked but there does not appear to be an appropriate event to
handle.

So far I have handled the "XLSheet.SelectionChange" event to achieve my
requirements BUT if the cell in question is ALREADY selected, clicking on it
will not raise the above event. I have to click elsewhere so that the
selection changes, the result being that data is added to the worksheet in
the "wrong" cell.

Am I missing something that should be really obvious?

I am using vb.net express (2008) and Office 2007 (interop).
