Can you run Lectora on a 64-bit OS with Windows 7?

Hi,

I just got a window 7 with OS 64-bit. I reinstalled Lectora inspire on it and tried to run an exiting lectora file, however, the menu slide out incorrectly- it slides out every time enter into new page. It should be slide out when the total pages in chapter meet.

It works fine when published in window 7, OS 32-bit.

Is the 64-bit the reason? Does anyone knows?

Thanks.
