HELP!! IE giving me format problems

[makt25]

I have a semi-transparent background to the content of my website. In Firefox, everything looks great, but when I open it up in IE, parts of the background are transparent, and other parts arent! Can someone tell me why this is happening?? My website is www.tracymak.com

Here is the CSS:

/*Rounded Background*/
.dialog {
width:90%;
margin:0px auto;
min-width:20em;
max-width:700px; /* I only cut the left background images out to 800px. You could do much larger, etc. */
}

.dialog .hd .c,
.dialog .ft .c {
font-size:1px; /* ensure minimum height */
height:11px;
}

.dialog .hd .c {height:11px}

.dialog .ft .c {
height:14px;
}

.dialog .hd {
background:transparent url(http://www.tracymak.com/images/tl.png) no-repeat 0px 0px;
margin-right:14px; /* space for right corner */
}

.dialog .hd .c {
background:transparent url(http://www.tracymak.com/images/tr.png) no-repeat right 0px;
margin-right:-14px; /* pull right corner back over "empty" space (from above margin) */
}

.dialog .bd {
background:transparent url(http://www.tracymak.com/images/ml.png) repeat-y 0px 0px;
margin-right:14px;
}

.dialog .bd .c {
background:transparent url(http://www.tracymak.com/images/mr.png) repeat-y right 0px;
margin-right:-14px;
padding: 0 15px 10px 15px;
line-height: 22px
}

.dialog .bd .c .s {
margin:0px 8px 0px 4px;
background:#000 url(http://www.tracymak.com/images/ms.jpg) repeat-x 0px 0px;
padding:1em;
}

.dialog .ft {
background:transparent url(http://www.tracymak.com/images/bl.png) no-repeat 0px 0px;
margin-right:14px;
}

.dialog .ft .c {
background:transparent url(http://www.tracymak.com/images/br.png) no-repeat right 0px;
margin-right:-14px;
}


/*Rounded Dialog Box Content Style*/

.dialog h2 {
/* header */
margin:0px;
padding:0px;
margin-top:-7px;
font-family: "Trebuchet MS", Arial, sans-serif; text-transform:uppercase; color:#00CC99; font-size:24px; text-align:center;
}

.dialog h3 {
/* header */
margin:0px;
padding:0px;
margin-top:-7px;
line-height:22px;
font-family: "Trebuchet MS", Arial, sans-serif; text-transform:uppercase; color:#00CC99; text-align:left
}

.dialog p {
margin:0px 0px 0px 0px;
padding:3px;
font:0.95em/1.5em arial,tahoma,"sans serif";
}

html>body .dialog pre {
font-size:1.1em;
}

/*End Rounded Dialog Box Content Style*/
