I am using the greybox theme for my simple image gallery. When I click on the thumbnail the larger image is displayed along with the top navigation bar. However, the close button in the top far right is consistently partly off the screen. I don't want the user to be unable to locate the close button and consequently be unable to return to my site. Please advise accordingly as to how I can remedy this problem. Thanks.

This could be an conflict between the css used by the greybox theme and the template...
If you use some other theme of the SIG you have the same issues? ( long screen )
