crashes on my side as well

win XP no packets in place.
so I run my debugger: (sorry german)

Der Thread 'Win32 Thread' (0x818) hat mit Code 0 (0x0) geendet.

well it tries to do a read function in the memory, were it has not business
to do :-)
and this causes the system failure and the program has to be restarted
 
7FFE02FC  add         byte ptr [eax],al 
7FFE02FE  add         byte ptr [eax],al 
7FFE0300  mov         edx,esp 
7FFE0302  sysenter         
7FFE0304  ret              
7FFE0305  pushfd           
7FFE0306  or          dword ptr [esp],100h 
7FFE030D  popfd            
7FFE030E  ret              <---- here comes the downfall :-)
7FFE030F  mov         edx,esp 
7FFE0311  syscall          
7FFE0313  ret              
7FFE0314  nop              
7FFE0315  pushfd           
7FFE0316  or          dword ptr [esp],100h 

so it comes from:

        7ffe0304()      
        ntdll.dll!77f6f4af()    
        ntdll.dll!77f6e265()    
        mshtml.dll!74877f58()   
>       mshtml.dll!74877576()   
 that was it on my machine.....

reproduced it twice.
but i could not see what this behavior evoked in the html code?!?!
first i thought could have something to do with the embedded scripts, but
doesn't seem so....   

btw not using Outlook (and i could not see why this should have something to
do with it)
