It is when nothing much has supposedly changed, and it's almost doubled in size. Call me suspicious, but, that's not normal. Particularly for a security product! I'd like to hear from developer's... P.S. You want to see optimized coding - check out Elite, Rev's, etc.from BBC Micro day's. Modern coder's have it easy + are lazy! P.P.S. Even if they're not lazy - I'd be interested in what made such a massive increase in size ?
