I'm having a bit of an issue with the Promotion Slider in that some of the images are appearing on top of each other. They're fading correctly, but you can still see part of the previous image behind it for just a second or so. You can see the effect here, the slider is in the sidebar on the left hand side:
Some of these images are PNGs with transparency - could that be causing the problem? The thing is when I first installed this plugin that didn't happen at all and I was using PNG images then as well, so I'm assuming it's something that's come in with an update to a newer version.
Any help would be massively appreciated. :-)
