The "virtual dog" ate my homework

Depends on the machine. On a slow, outdated school computer I was able to handle a 20mb world with 4 full length songs on it (.mp3 format) without bugs or lag.

On my home computer, I can handle more, but I'm not sure how much more, as I usually keep my worlds under 20mb so I can post them.

My suggestion is to stay around 20 mb. Any larger is taking a gamble (with the risks being slowness, and possibly bugs like the ones you mentioned).

If you really like adding extra objects to your world and feel that large files are necessary, absolute maximum should be 60mb, with any offscreen objects' isShowing properties set to false.
