link opens with no scroll bar

I have a link to SurveyMonkey in my results page success layer. When I check this link within Storyline it works fine. The survey opens in a new window with a scroll bar on the right side. When I publish the course it doesn't work. If I pass the test and click on the link to do the survey it will open but with no scroll bar. you can only see the first 2 questions. If you zoom out on the screen you can see they are all there. This only happens in Firefox and IE. If I use Chrome it works fine. The survey will open in a new window with a scroll bar. I know the problem isn't in Survey Monkey because I copied a previously used survey that works as it should. I have used the survey monkey link in numerous courses built in Storyline with no problem.

Any ideas???
