Horizontal spry menu does not open correctly

I have a horizontal spry menu which is a java script furnished by Dreamweaver CS5. You are supposed to click on a menu item and the submenu items should open next to the menu item. Instead, in the exe file generated by HTML Executable, these submenu items open at the very bottom of the screen. What to do? (There is a public version of this at http://www.aei-our.com/chapters/chapter_index2.html, which shows how it should work.)
Many thanks to anyone who can help!

To see the correct behavior of the spry menu, you have to view it in IE.

Which version of HTMLEXE and IE are you using?

HTMLEXE 4.6 and IE 11.

We’ll release HTMLEXE 4.7 which should fix the problem soon.
