I would expect that your pane width is being determined by the contents of the larger module. Some modules have fixed widths, some shrink around their contents, and some expand to fill the space. Clearly your smaller module is not expanding to fill the space made by the bigger one.

The workaround will depend on exactly what modules and contents are being used. If these are simply text/html modules containing plain text then have a look at the titles. The width of the pane will be set by the longer title as it stetches the container out wide.

Thanks for the tip, I'll try that. I currently have the rightpane fixed at 170 pixels. The two modules in the right pane are a text module and a links module. The links module is the one that is larger (lengthy title) that is stretching the pane

The site is an intranet so I can't send a URL.

But here is the css

#pagemaster{
 width: 96%;
 
}
.ContentTable <!--table that holds the panes. THis skin has a left side vertical menu-->
{
 width: 100%;
 height: 100%;
 border: 0px;
 border-collapse: collapse;
 padding: 0px 0px 0px 0px;
 vertical-align: top;
}
.TopPane{
 vertical-align: top;
 text-align: left;
 background-color: transparent;
 padding: 0 6px 0 6px;
}

<!--Left Pane has the menu-->
.LeftPane{
 width: 160px;
 vertical-align: top;
 text-align: left;
 background-color: transparent;
 padding: 6px 0px 4px 0px;
}
.ContentPane{
 vertical-align: top;
 text-align: left;
 background-color: transparent;
 padding: 0 6px 0 6px;
}
.RightPane{
 width:170px;
 vertical-align: top;
 text-align: left;
 background-color: transparent;
 padding: 0 6px 0 0;
}
.BottomPane{
