Horizontal Scroll only works in Compatibility Mode in IE

Can you post more details like OS, IE version, etc?

I'm having this same problem using 6x-2.0 version. I can fix by using compatibility view but not all viewers will know to do this.

Please post a screenshot, & the export of the view.

I'm experiencing the same issue on IE9. Only the first entry displays in the ticker, but in the Views setup screen, it displays all the values.

Issue only occurs in IE9. All other browsers display correctly. When I switch IE9 to compatibilty mode, it displays correct.
I've tested with 7.x-2.0 and 7.x-2.x-dev using Chrome, Firefox and IE. It seems to work fine in earlier versions of IE

Find view export below:

I have the same issue, with an added problem. on page load, it lists all of the ticker items vertically, not applying the styling until I hit refresh.
I've had issues with IE not floating things properly if there isn't a set width. This could be the case here.

I have the same issue, but I'm not so familiar with css.
To which file do I need to add this?
