i have a problem with the subnavigation on the middle right of the website i am working on. it is positioned as fixed and works like it should in 90% of the cases. but with some combinations of browser and operating system (chrome 48.0.2564.97 M and windows 8.1 for example) the navigation is being positioned absolute over the whole page and moves when scrolling. is anyone of you aware of these problems? and is there a workaround to fix this?
