VSTS 2008 Issue 1 :- Load test with Think profile, system is applying the thinktime in the beginning of the run

Issue: If we are declaring a load test with Think profile, system is applying the thinktime in the beginning of the run.

Detail: We have a load test using Unit Test with following configuration
Think time= 1 hr
Step load
Max. Users= 100
Step duration: 10 sec.
Step User count : 1

Once we start the Test using VSTS 2008, the system is waiting for 1 hr, mean time all the users getting initialized and ready to start the test.
At the end of 1 hr, all users start the test at once, against the expected step pattern.
Because of this, we need to wait 1 hr to get the first request executed.
This issue is not there in VSTS 2005, where the thinktime is applying only after the first iteration.

My requirement is that, we need a think time in between the iteration, not in beginning. VSTS 2008 is taking the specified think time in the beginning also. In VSTS 2005, if I specify a think time of 1 hr, after the first iteration it will wait for 1 hr to post the next request.But in VSTS 2008, it will wait for 1 hr before the first request. I want to eliminate the waiting in the beginning of the test.
