Hello Martin,
I tested the following code with the latest version of the assembly (2009.2.701.20) but I was not able to reproduce the problem you describe in IE8:
Could you please provide additional information what happened that made
the problem reappear - for example, the upgrade to the latest version
(2009.2.701.20) resulted in this. It would be best if you could open a new support ticket and send us a simple running project that demonstrates the problem in IE8. That way we will be able to research what causes it.
Greetings,
Tsvetie
