I'm having a problem with the expanded image in Highslide. For some reason, I'm getting some white/gray (#EBF6FF to be exact) background appearing when I bring the mouse close to the image around the outside. Here's a link to a screenshot.
It also does it on the sides (a white box/background appears, jutting out 13 pixels on either side, beginning at the bottom edge of the area shown in the image above), and the bottom, although for the bottom you need to mouseover outside the caption area, along the lower right and left corners of the image. The affected area is 13 pixels beyond the top and sides of the image. I've gone through my CSS and can't find any 13 pixel padding, and also can't find any references to #EBF6FF. Has anybody seen this before?
I've used Highslide in the past with the glossy dark border, but I wanted to switch to a borderless look. I'm not re-using any of the previous HS code (with the glossy border). I started this one from scratch using the latest version (4.1.13). Everything else is working fine, the only problem is with this unwanted background appearing on mouseover. Unfortunately, I'm still developing this on my localhost, so don't have it live to view on the web. But I can provide any code that you may need.
Thanks in advance for any help/suggestions anybody can provide!
Edit: This site isn't finished so I can't upload it yet, but here's a link to a video I took showing the issue.
