Web interface too wide for display

[lchiu7]

This is a strange one. Using the latest release of GB and Firefox as the browser to run the web admiinstration, I am finding that while the browser interface works, the screen image is actually stretched over the right hand side of the screen. To explain - the program listings show up okay but the fields for setting the date and advancing the schedule forward require that I scroll the screen almost one screen width to see.

I am using the standard web adminstration tool (so style sheets etc. presumably)

Any ideas?

Thanks

Larry
