Stack And Tile Bugging Out

[impurity]

I'm playing WPN and bovada, and using stack and tile for WPN. What happens is after 30 minutes, one table becomes "stuck." In other words, it's always in front, and any time I click on another table, it takes me immediately back to the table.

I always end up having to close the table, and if I try to add any other table, the same problem happens.

Then 30 min later, same problem occurs.

Any ideas what the problem is? I find it hard to believe this hasn't occurred before, because it's happened to me every time now.
