Downloading categories... generating preview

i see this almost each time i’m clicking on my auctions. and this takes almost a minute each time before i will be able to edit something (i’m on 80 megabit/sec channel).
why GS needs to reload categories each time?

GarageSale only downloads the categories if they have changed since the last time checked. Perhaps you are switching between different eBay sites when selecting another listing?

Each eBay site maintains its own category structure, which seems to change at least once a week.
