cProjects with IE7

Hi,

I'm trying to use cProjects with IE7. The problem comes when I go to the "Evaluation" tab or the "Resource Planning" tab. IE7 opens a new window to display the content of these tabs, leaving the main-window with a white space "Loading..." while the new windows stays empty. I solved that problem for some time using Firefox 2, but since I updated to Firefox 3, cProjects became very ugly and I was left with no options.

Does anyone got the same problem? Any solution?

Thanks,
