Double click on task opens empty

[froyo]

Hi all,

When I am in the "Project information" tab and create a new task double-clicking on a blank area, I am able to write all the information about this new task. Nevertheless, when I double-click on it afterwards to edit the properties, the dialog contains only blank information.

I have also tried to right-click and select "Modify selected" but the contents is blank as well.

Am I doing something wrong?

Thanks
