OK
Found your Store here....
http://stores.ebay.com/My-Outlet-ShoppeI looked at the 3 Buy-It-Now listings and didn't immediately see any width problems. I also didn't see any Auctiva templates, i.e. no tags or other embeds. There's isn't even an Auctiva Scrolling Gallery (SG), although it looks like the auction listings got rolled into Auctiva recently (got the SG). I do see Auctiva hosted images in the listings. They appear to be the 400 x 300, which "might" be a little crowded (like the Farm Hen listing) with a lower res monitor. Note, I'm using 1152 x 864 on mine for viewing. Just to check, I switched to 1024x768 and can see how the text stacks narrow (which confirms my suspicion). I sometimes drop my monitor all the way down to 800x600 for checking what a listing might look like for that (almost) worst case scenario. eBay advises that res as minimum and 1024x768 for best viewing. With the Store Categories column on left, it does narrow the item's field and images, et. al. can suffer. You may need to consider that problem for futher listing development, as Auctiva's free images embed in the Description section, where ebay appends them at bottom.
Did you create these new listings from other than new Auctiva's one-page lister?
Also, what do you have your monitor resolution set too?
I'm assuming that your prior reference to "template" is meant to reference Auctiva hosted images, or am I missing something?

Edit: I just spotted a very-wide issue due to three side-by-side images in one of the Teddies (top one on the Store page).
