On padding problems in Internet bloody explorer…

If anyone can find me any kind of documentation on the differing treatment of the paragraph tag on IE for Macs and IE for PCs (with specific reference to CSS, padding and margins), then I’d really appreciate it if you’d mail me. And if you need an example – compare and contrast on a Mac and a PC. This issue appears to be one of the main problems that must be solved before effective permalinking becomes an option.
