[questions]Is it possible to edit Winmac and about Safari clones

[Jaggedfel 0]

Guys I have 2 questions here and to keep from flooding the boards, I was just going to ask them together. I have Winmac downloaded on my PC. Is it possible for me to edit an ini file somewhere to get it to have open up the apps I want like when I click burn disk (which is currently grayed out). On another note, I like the Safari clones. Right now I'm using Savanna, and I was just wondering, besides the IE problems it has since it is just a shell for it, do the shells themselves have any more vulnerabilities in them?
