Trouble playing Dominoes and hearts

[BalletDancer13]

I have been trying to play dominoes for a while. And hearts worked last week but won't this week. Every time I go to sit down there is a thing that pops up and says I have a popup blocker but it's never happened before. If I go to play something like Jungle Gin it works fine. I've tried holding down the Control key. What is there to do? I emailed helpful pogo and they said that it was a popup blocker but why would it work with Jungle Gin (it just lets me sit right down) and not work on the others?

Try the shift key. Some blockers use the shift key.
