I had a look and see what you mean.

Sending the popup command in a "send ... in  <time>" message seems to  
stop the card script firing. That might help you.

on mouseDown
     send "popitup" to me in 150 milliseconds
end mouseDown

on popitup
    put the long id of btn "_Player Menu" into mButton
    popup mButton
end popitup

But even with this, there is some odd behavior. The timing of the  
popitup message, and the way in which you press and release the mouse  
affects the message sequence. However, this may not be a problem. (It  
will be if you need to respond to the mouseUp message on the Player.)

The popup behavior seems to "suspend" mouse messages in some way.  
This is probably because the next click outside the popup will  
dismiss the menu, and not cause the normal mouseDown/mouseUp messages  
to be sent. However, in your stack, perhaps because the popup command  
is happening in the mouseDown handler, the Player's mouseDown is  
being "interfered with" in some way. To be honest, I'm not sure what  
should happen to messages in this situation. But getting a mouseDown  
in the card is weird.

It reminds me a little of what used to happen (it may still do this)  
when you try to poll for the mouse being released in a mouseDown  
handler (repeat until the mouse is up). The mouseUp target would not  
necessarily be the object which received the mouseDown.
