Hover Menu Issue: IE 7 moves items to the right (CSS)
Hey everybody,
I am a student and while creating a website for my economics club, I encountered a problem that is beyond my head. I usually create the CSS part by somewhat trial-and-error and now Internet Explorer 7 is my only last problem.
I know there have been similar issues before on here, but I'd really appreciate if someone could tell me where my mistake is.
I based my hover menu on this example: http://www.xs4all.nl/~peterned/examples/cssmenu.html
Internet Explorer 7 displays the pop-up menus a couple of pixels to far to the right, hence they are not clickable when you move the mouse to the right. I am also aware that IE6 doesn't display everthing correctly but as long as it works I don't care.
If anyone could tell me what to change in order to make it work in IE7 (without braking the functionality in Firefox, Safari, IE6...), I would be very glad.
Because this is really important to me, I am also willing to give away a lot of points.
In the Code Section, there are two parts: one is the HTML-Website-code, the other part is the contend of a file called "csshover.htc" in order to make things happen on IE6.
Please excuse my English, I am German.
