Our vendor Captivates are now displaying "thumbnail" size in newer browsers like IE11, Chrome. Why?

Question

Hi,
We're using some 100+ Captivate tutorials supplied by a vendor. Our user base until recently was all IE8, IE9 browsers, and the Captivates displayed without trouble. Now we have users with IE11 and Google Chrome trying to launch these Captivates (using the .htm in the launch url) and the Captivates display in tiny, unreadable thumbnail size. We've found a workaround in that we can launch the Captivate by pointing the URL at the .swf file instead, and they display normal size. But before we change 100+ URLs and bring on who know what other problems... why is this happening?  Is there a browser setting we can change instead? What do we lose launching with the swf instead of the htm? Thanks!

Add this just above the </head> tag in the html page as see what happens.
<style type="text/css">
html,body {
height:100%
</style>
