TFS 2010: Click "View Reports" twice?

At first, after fixing the reports on our TFS 2010 report server, I thought reports weren't running properly when changing the parameters of the report. For instance, I would change the "From (date)" field, and then click "View Report" (or hit Enter); the screen would flicker, but no reports would show. I found that if I simply clicked "View Report" (or hit Enter) again after this screen flicker, the report would load.

As it turns out, Microsoft posted some time ago about this being a normal function:

Thank you for your feedback.

We have reviewed your issue. The issue that you have reported is by design because we do need a click outside of the textbox (and that could be the first View Report click) to validate and calculate any parameter dependency. And then after that, you need to click View Report to run the report.

Thank you.
