I found
[EDIT: THE REG KEY] that is associated with weather, here is the provxml for it;
<characteristic type="HKCU\Software\HTC\Manila">
<parm name="Weather.ServerURLOverride" datatype="string" value="
http://weather.not2advanced.com/htcweather/forecastdata.php?ac=XDADevs&locCode=%25ls&version=1&device=innovation"/>
</characteristic>
The ServerURLOverride was missing intially but once I added it, things would update. If you add that prov xml into the hd manila cab it will be 100% rockin'. I just had to delete the first city in my list and then readd it and they all worked.
Ya the zoom buttons only work the way you described (kinda useless) I just installed it to try and get other stuff going.
Thanks for the cab fix. I'll test it out for you with [UC] and a hard reset (my manila files are so messed right now from trying to fix stuff haha). AWESOME SIDE EFFECT OF THIS CAB: MY BG4ALLPages works with my custome clock
