Adsense and browser cache?

[AndrejX]

About week ago, I noticed very strange behavior with ads on my site.

I visit my site few times daily to check situation and noticed that I can see targeted ads only in first visit for
that day. In every next visits I can see only PSA ads - until I clear my web browser cache when targeted ads started
to show again.
Is this some new system feature or is something wrong with my site?

I suspect it's more likely something wrong with your browser rather than your site. This has never happened to me.
