Bug with link dialog box

I have found a bug where the dialog box doesn't appear if the surrounding div is too big and floated to the left. If 1024X768 resolution, any width greater than 1003 and for 1280X1024, width greater than around 1240px then if you press the link button, the screen fades as if to show the dialog box but it doesn't appear (perhaps it is being placed off screen). This is happening in Internet Explorer 6

Here is the code under screen resolution of 1280X1024
<div style="width:1250px;float:left">
<!-- #INCLUDE file="fckeditor/fckeditor.asp" -->
<%sBasePath = "fckeditor/"
Set oFCKeditor = New FCKeditor
oFCKeditor.BasePath = sBasePath
oFCKeditor.Height = 600
oFCKeditor.width = 670

oFCKeditor.Value = ""
oFCKeditor.Create "Content"
%>
</div>
