repeated Account Sign In requests whilst I am listing. Why?

I am increasingly getting the Sign-In to you account page whilst I am listing.  Sometimes two or three times - usually when I am attempting to upload photos or finalise the List Your Item pages.  And sometimes I get totally thrown out.  anyone else get this?  Is this an eBay issue due to heavy traffic at times, or could it be just a problem with my ISP?

Yep, damn maintenance glitches! I listed an item half an hour ago. It's visible when I click on the link from the email confirmation that is telling me my item is listed. It is not visible in my store, in the store category where it is supposedly listed or anywhere else for that matter :_|
