Cross OS problems.

Why same verision firefox browser renders differently in PC to that of MAC

[hrudayamm]

While I am testing for browser compatibility in MAC and PC. I found that <input type="file" size="30" /> is rendering differently in MAC to that of the PC (both using the same firefox version). I just wanted to have a fixed width for that input element. Tried to use style="width:200px;" but that worked only on IE, cannot use size="30" because of the above problem.

Please Help! :(

I can't say I've come up against this, but that's because I've completely given up on styling the file input. t's almost impossible to do anything x-browser to it.
