I think you better make a descendent of these classes that is specific to IE.

I have not yet found a good approach to cater for browser specific events.
I have tried with {$IFDEF}, but that is only good till we have compiled
units. After that, it will also no longer work.

But till we have a good solution, the web unit must contain the lowest common denominator.
