setTimeout freezing
 

I've got a fairly simple javascript website which some of the time works perfectly, but every few attempts it will freeze on this command...

setTimeout(partner2, 3000);

If anyone knows why this would happen, and why it only sometimes happens, i would greatly appreciate it!

Thanks all.

A second instance of setTimeout() called while the first is still active? (Within 3 seconds).

I use quite a few setTimeout() commands in my code. But only in different functions so I'm not sure how they could conflict with each other.

These functions are sort of on a loop, but each connecting to the others using setTimeout commands.

The completion of the 4 functions are looped 10 times and has frozen on different loops and even not at all, but when it does it's always at the same stage (eg. from function 2 to function 3).
