        Hello,

Sorry for coming late and maybe off-topic.

In most cases, exception-based shellcode debugging issues on Windows are 
due to the fact that Unhandled Exception Filter is *not* called when a 
program is being debugged.

If you are using OllyDbg, trying to hide the debugger with some cool 
plugin like OllyAdvanced.
