I have started using httrack 4.31, however after running for some time
application caused following debug assertion:

---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Assertion failed!

Program: C:\BPS\htttrack4.31\SlowMonitor.exe
File: f:\bps\httrack\httrack\src\htsback.c
Line: 267

Expression: !duplicateEntryInBacklog

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts

(Press Retry to debug the application - JIT must be enabled)
---------------------------
Abort   Retry   Ignore   
---------------------------

Please let me know your comments.
