[Plugin: NextGEN Gallery] NextGen Gallery Widget vs Internet Explorer

I am using the Nextgen galleri on three of my pages:
https://test.soknedalbakeri.no/kaker/
https://test.soknedalbakeri.no/bryllup/
https://test.soknedalbakeri.no/brod/

I use three different galleries on theese different pages and they appear correct. My problem is the Next Gen Gallery Widget in the right meny which acts weird i IE.

In Google chrome and Safari the widget is just the way i want them. (four small images side by side). But in IE they are big pictures. Why? I tried to change the thumbnail size in the widget but IE wont listen.
