I've created a toolbar button for IE6 that changes the proxy
settings from 'Direct' to 'Use a proxy server' and back again. What
I'd like to do is change the mouseover tooltip to show the action
that will happen when the toolbar button is pressed (i.e. if the
proxy server is currently set to direct then the tooltip should say
'Set proxy server to ON').

Any ideas how to make this happen? Changing the registry setting
SOFTWARE\\Microsoft\\Internet Explorer\\Extensions\\guid\\MenuText
only affects the tooltip when you restart IE...

IE takes text of the tooltip equal caption buttons, find its button and
change her caption
only for example ...
