Okay being the guys who always gets the weirdest issues. Here is the situation...

I have built a html form and am using CSS to style the form. Here is a code snip from the HTML form for an idea of who i built it, and below is is part of my style sheet. The problem is that if I include both parts of the css styles Dreamweaver CS3 or CS4 on two different machines locks up when previewing the form. This crash only happend in Dreamweaver, if you open the html page in IE or Firefox wit will function fine.

I started with css sheet and commented it out until i figured out that i can have label or the li entry but not both, then i went further and isolated it down to that i could have both with out crashing if i change the li width to auto instead of 100%. Anyone have any thoughts? FYI i got the style code from a Sitepoint artical on forms and CSS.
