The 3.09e release is available, and fixes a crash 
problem when reaching compressed-error pages (this may 
happend on some websites)
Please update you HTTrack release is you encountered 
problems.

However, another error has been reported, which 
crashes the engine randomly (the crashes never happend 
twice on same location - therefore 'continue an 
interrupted mirror' works and will finish the job 
properly) - if you have detailed information, 
reproductible crashes (this would be the best!), 
please email me!. Thanks
