Threading excel

Can I have multiple threads in Excel. I need a counter to show the time elapsed. The thread would have a loop which would update the counter and then sleep for a second. This would (hopefully) take care of excel freezing up while calculating. Along that line, is it possible to have excel update while it calculates. By updating, I mean that the screen would continue to update, rather than freezing. However, I have not tested 2010 and so have no idea whether this is still a p开发者_StackOverflow中文版roblem (it is in 2007).

The answer is no.
