Fault in scrolling image

IcedB

There seems to be a fault when tiling images. Two thin lines of background colour are showing behind a tiled image. I've had this in two projects now, the artwork seemed to work ok in previous version of gamesalad but I just began building this new game in this version and found this problem. Any ideas? I've included a screenshot to highlight this:

@uptimistik cheers, massive demotivator for my game art creation tho, will have to switch projects until the fix:(
