Disable panel resize on browser window resize

Hi, I got a issue with the panels resizing (width) when the browser window resized.
below is the dashboard as it should be…

below is the same dashboard but with the browser window maximized

As you can see the width of the panels changes.

Now if I set the panel widths while the browser is maximized, and then resize the browser, the panel width become too small to see all the data within the panel.

So my question is weather there is a way to stop the resizing of the panel?
