I normally try to search for topics to see if there is known solution, but I am not sure where to begin with this one. I have a pretty good understanding of the zen-cart system, but this one is odd and i need a fresh set of eyes to resolve this issue.

When you change categories in my store the custom left side background image flashes horizontally across the screen for a brief second even though i have it disabled in the store configuration and then it disappears.

It seems to do it every time you switch categories. Does anyone have any insight?
