Re: User cancel feature

In reply to the "Clicking the Globe" thingy of Mosaic

When data is copied from a server (HTCopy()), the
functions HTClearActiveIcon and HTCheckActiveIcon()
determine if the "globe" has been clicked. If it has,
an interrupt flag (intr) is set, and the interrupt
handler is invoked... thus displaying the "Data transfer interrupted"

Hope it helps.
