I have several blogs and everyday I am touching with Google webmaster tools. Google finally cached my page on 11-May-2009 and they updated my external links beginning of this month. But After April 26th, They not updated "Top search queries" (Under "statistic") How about your account ? Something wrong?
Yea ive got the same thing with my sites dont worry about it, Google probably have an issue with their stuff. Ive seen it happen a few times
