SGS - Rendering differences Internet Explorer and Firefox

Hi,
Using IE 8 and FF 3.6 on same Windows XP machine, sane SGS application.
Displaying same module/page.

Some differences are noticeable.

1.The ID column in the attached screen shot, is single character column width on IE while 3 char on FF. This creates a major visual difference between the two. Please note the two browser windows s were adjusted to the same width on the screen, so expectation was for same display.

2. Please note that boxes around screen items (like view names, search box, SGS main menu line, folders, categories) are square on IE while they have rounded corners (one or all) on FF. The \"select\" box on FF has a square around, while on IE seems to have 2 sided shadow.

I personally prefer the FF look and I wonder if SGS can be adjusted to achieve this same look on IE?

Thanks,
Easy
