And it crashes the browser!

My bosses went in for a meeting with the client and obviously they had the site running for the duration, after about an hour however, the site just crashed, the even had to reboot the machine to get it working again.

Not sure if anyones ever tried to leave their flash sites running for an hour or so, but if you have do you get the same problem?

Is this a known issue with the flash player? or have I simply written rubbish code?

Obviously I hope its the former but I'm more than happy to hold my hands up if it's the latter!

Basically my question is: Is there a known issue with the flash player whereby if you leave the browser running for an extended period of time it will crash the browser?

Any help/info greatly appreciated,

Paul
