Hmmm...yeah that's a well known issue.  I'm not sure if that is a feature or a bug, 
but it is  a 
common behavior.  Also, doctype issues can affect this sort of thing because of the 
way 
browsers handle nonstandard rendering modes (which is of course "non-standard").

Check this out: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.jsbsim.org

You will want to decide what your target doctype really is and correct this before 
calling the 
problem solved. 

This is somewhat unrelated, but trying the page under Safari, the buttons don't 
disappear after 
the mouse leaves.  Run the mouse up and down the list and all the buttons show at 
once.  It 
seems like I had something similar working on wreath.com years ago...so you could 
check the 
way back machine (I just looked and it wasn't running) at www.archive.org.

Best,

Jim
