[web2py] Web Shell problem on Mozilla Firefox 5 and Internet Explorer 9 (PC with Vista)

[Valter Foresto]

I noted alternate functioning of Web Shell on Mozilla Firefox 5 and Internet 
Explorer 9 on a PC with Vista installed OS.
I currently use the last Version 1.97.1 (2011-06-26 19:25:44) of web2py.

Anyone noted the same problem ?
