Form, input, onMouseOver - onMouseOut and browsers

I've a form (POST) with this INPUT (a line), in a JSP file:

<INPUT TYPE="submit" VALUE="Executar" name="1" id="Execute"
style="visibility:hidden" onMouseOver="window.status='URL: http://ift.tt/1C8UbzA'" 
onMouseOut="window.status=''">

It works with:

• IE 6 and Mozilla Firefox 36.0.4: See my onMouseOver.

It doesn't work with:

• 
  

  Mozilla Firefox 9.01 and Chrome 41.0: Nothing it appears.

  
  


• 
  

  IE 9: It appears '*http://.rhcloud.com/directory/filename.jsp#'

  
  

EDIT 2 APR:

• My form (simplifyed) is this (without my textarea):

:

<FORM action="#" METHOD="POST"> 
... // Initial code
</FORM>

I would like to improve my INPUT (for all browsers) with only '*.rhcloud.com'.
