Non-maximized window display error on FishEye 2.6.0

The same problem happens on both Firefox 4.0.1 and Internet Explorer 9:

If you go to FishEye Administration >> Project Settings >> Projects with a Firefox 4.0.1 maximized window, it will display correct.
But if you unmaximize it, some columns will be hidden, and no horizontal scrollbars will be displayed.

If you go to FishEye Administration >> Project Settings >> Projects with an Internet Explorer 9 maximized window, it will display slightly incorrect. The last column will crop some letters of the "Application Links" link. It will display only "Application Lin".
And if you unmaximize it, some columns will be hidden, and no horizontal scrollbars will be displayed.

Please see the screenshots attached for more details.
