Question : Strange Vista Sidebar Gadget Problem

So I got into developing a vista sidebar gadget and ran into a weird problem...The gadget uses simple ajax to call a server side script on a sub domain I have and the xmlHttpRequest.open() call in the gadget .html javascript gets a "Access is Denied" error. But here is the kicker...it only gets that error on Vista Home (basic or premium). On Vista Ultimate or Vista Business it works fine...Im at a loss. Im positive its the version that is causing the error because I have tested across multiple internet cnxns and mulitple Vista Home and Ultimate/Business installs with the same results. Anyone have any ideas at all?

Note: Iam using REST.  I have tried turning off all antivirus and windows firewalls.  I have tried adding the server domain to the trusted sites in IE7...(all these seem to be common problems I found when searching for a solution on the web before I posted here, so I thought Id mention as things ive already tried).

Thanks for any thoughts or help anyone has.

Answer : Strange Vista Sidebar Gadget Problem

Thanks for all the help everyone!  Im glad I pay for a yearly subscription so that I can figure things out myself with absolutely no help...not even a suggestion or comment.  Maybe I should quit my job and become a Hall Of Fame expert!   For those of you that would like to know how to package it so it doesnt get flagged as unsafe file and gets blocked, all you have to do is zip up all your files for the gadget and then rename it from *.zip to *.gadget and should be all set.
