redundant hang up from script message

[Clambuster]

I have a app which uses an animated gif on the third card of the stack with a transparent button over a map to go to the next card.
on mouseup
go to the next card
end mouseup

The card hangs up for about one to two minutes. It finally recovers with a message:
The handler: cREVGenral has reached the recursion limit of:400000. Execution will be terminated to prevent hang,

The message watcher repeats : cRevGeneral 10:57:03 AM for twenty or more times. After the stack starts up again it moves to the next card. I can't see anything which would result in a recursion. I'm not sure what would cause the cREVGenral message to be sent repeatedly.
