nole4ever,
1) The "Require Immediate Payment" issue has been confirmed as a bug and has been referred to our engineering department for correction. However, it will not be fixed until mid-June 2006.
In the mean time, if you would like to post these listings successfully through Auctiva, you can remove the "Require Immediate Payment" option.
2) I just tested out the "Save" function on the details profile page and it is working on our end. You may want to try clearing your cache via the following process and perhaps this issue will be resolved:
In Internet Explorer go to the Tools menu, click the Internet Options menu item, then click the "Delete Files" and "Delete Cookies" buttons.
In Firefox, go to Tools -> Clear Private Data -> Check Cache and Cookies -> Clear Private Data Now.
Remember to close all browser windows but one while clearing your cache.
I hope this helps=)
