sometimes i switch to google chrome instead of firefox just to try to narrow down the problem.
if the problem is also occurring on chrome (or ie) and not on other sites...there is an issue with auctiva.
the reason i try a different browser is that sometimes the updates just mess with everything. i have resisted the last firefox update because of these problems.
as lookandbuyme asked, please keep us posted with the support responses. if you haven't already done so, i suggest filing the support request before friday evening.
