I downloaded the latest version of Atlas and built a test page to see if TexboxWatermarkExtender would work with a validator. The code is below. When I click on the submit button for the first time (with no data in the textbox), I see correct behavior: validation fails, I see the error message, and the page is not posted back. If I make no changes and click on the submit button again, for a split-second I see a javascript error in the IE ("Sys.Application.findObject(...) is null or not an object"), and then the page is posted back. Needless to say, no validation occurs.
I am new to Atlas, so forgive me if I am making a rookie mistake somewhere:

We'll be adding this to the FAQ, too. Thanks!
Thanks a lot, will do. I missed your reply until now, sorry.
In case anyone is curious, this code only started working when I added an UpdatePanel
