I finally learned how to make the auto hide on Windows 7 work. I am not a techy in any way at all. But, I have been trying to get it to work for a week. On my computer.. It will work, if there isn't anything on the task bar that needs attention.. For
instance.. If there is update in MSN that wants you to install the update, then look at it, do it or not, but at least pay attention to it.. It will keep the auto hide from working. when you have paid attention to all the icons on your task bar and updated
the things that are asking to update.. Your auto hide has no reason to be stuck open on your desk top.. It will immediately dissappear when the task bar feels that there isn't anything important for you to pay attention to.
It's like a little kid asking mom for cookies.. they won't go away, until they are given a cookie.. So, the task bar is like a little kid... naggying and nagging, by not letting the auto hide work. I spent moret than an hour with my hp tech and he could
not figure out how to make the auto hide work.
So, I think this will work for you.. Go and click on all your icons and see which one wants you to update or pay attention to it.. It is most probably the MSN update icon.. I did not update all the requested updates.. But, I at least let msn see, that
I looked at it.. After that, the auto hide worked again..
When I see that my auto hide is not working, I always go to the msn update icon first, to see what it is naggying me about.. Good luck..
PS. see the May 10, 2011 reply, it says the same thing..
