## Special Note on Hangs

With Mosaic 2.0, any stage of any network query (with a couple of exceptions; see below) can be interrupted. Simply click on the twirling globe icon in the upper right corner of the screen at any time to interrupt an ongoing or hung network operation.

The exceptions are certain stages of a direct WAIS query, and hostname resolution lookups. But note that connections to down or nonexistent hosts, document transfers, and inlined image transfers can all be interrupted easily and cleanly.
