Washington State interactive ad never ends - stops play

I waited a while to address this issue formally, as I thought others would alert tech support, but it's been nearly a month ...

The interactive ad for Washington State tourism never ends.  When it appears, sometimes between games, sometimes mid-game, there is no way for it to end. There is no "skip this ad" arrow or even a "wait for it to end" resolve. It just stays there. I've even tried interacting with it! and nothing. It brings me new windows, but none of them end or allow the initial screen ad to resolve or go away and for play to resume.  I now consider it a dead-end and I restart Pogo.com if it appears, as many times as necessary until I get some other ad.  But it's annoying.  I can't be doing anything wrong, since I have tried more than once to  just let it run as long as it wants.  My computer shuts down and it's still there.  Something is wrong, some code is missing, something.
