Taskbar buttons, Sidebar & more issues...

OKay, since SP1 was installed I have noticed a problem I need help
figuring out. I am running hte following from day one and only noticed
problems after SP1 roll out.

300gb HDD (sata)
4GB Ram
AMD Athlon x2 dual core XP 6000+ 3.01ghz
Vista Home Preomium 64bit
SP1
dvd burner
asus MB
Nvidia GeForce 8500 GT 512mb PCIEx16

now what happens, is if my wife is logged on with her account and i log
on second my side bar does not load all I see is hte plus sign at hte
top ofhte sidebar and the transparent outline of the sidebar, real
quickly it flashes all of my gadgets but they go straight to the
background and are not visible once loaded. then any windows you open do
not show up in the task bar at the bottom. If you hit the view all
windows button in the quick launch it rotates all windows and shows you
everything thats open. otherwise all you see is the window on top. If
this makes sense to anyone and you can offer some help please let me
know thanks!


oh and this happens when i logg in first everything loads fine then whe
she logs in it does this to her so it seams like whoever logs in first
gets everything loaded properly. so it requires a reboot everysingle
time you log in, in order for these two functions to work properly.


also side note..how many windows can be open at once with vista 64? any
one know...it seems to very on my sistem as well...some days only 5
windows can be open others 45 windows can be open ( I tested it)
