How to set a fixed (pixels instead %) width in portlet in Cognos Connection?

[DavidAlv]

I have a Page containing 2 portlets in Cognos Connection, I need at least one portlet to have a fixed width, I mean, a width set in pixels instead percentage. Does anybody have an idea of how to do this?

When I open the Page properties, I can only modify the portlet's widths in percentage, but not in pixels.

I've already tried setting the report's width in report studio in pixels (i.e. 300px), but when i decrease the size of the window, Cognos cuts the portlet content of that portlet.

Thanks in advance for your help!
