I've fixed this issue today. The problem was that win2vnc and x2vnc
requested screen updates only when a user moved to the second (vnc)
screen. If the client disconnected before receiving the first update,
that caused the problem here:
vnclog.Print(LL_INTINFO, VNCLOG("Hextile encoder stats: dataSize=%d, "
"rectangleOverhead=%d, encodedSize=%d, "
"transmittedSize=%d, efficiency=%.3f\n\n"),
dataSize, rectangleOverhead, encodedSize, transmittedSize,
((((float)dataSize-transmittedSize)*100)/dataSize));
When the dataSize is 0, there is a division by zero. While Visual C++
runtime does not make the program crash (is just writes something like
"efficiency=-1.#IO"), the Borland C++ runtime crashes.

Thanks for the info that helped me to fix the problem. The fix will be
included into the next TightVNC release.
