CFGrid Headers Invisible in IE until mouseover

My client uses CFGRID and IE a lot (yeah, I know) and I have been tasked to solve this problem.

When the grid first comes up in IE, the headers are invisible; mouse over them and they'll appear and stay on until you move on to a new table or refresh the screen.

Firefox and Chrome do not have this problem.

To make matters worse, my client has disabled the developer tools access in IE so I can't drill down to the CSS and look for a solution that way.

I am trying to find a cfgrid.onload solution, but apparently the documentation is sparse on the methods available in cfgrid (know where they are? Please enlighten me!)

I stumbled across .refresh() and updateHeaders() but I cannot find their proper syntax and just what the heck they're supposed to do.  I know, lame, but try RTFM when you can't find TFM!

My first try was to create and OnLoad this:

function IEReload() {

     var grid = ColdFusion.Grid.getGridObject('mygridname');

     grid.updateHeaders('mygridname');

     grid.refresh('mygridname');

}

which does not work.

Ideas welcome!

Thanks,
