This looks like it’s something to do with the Action that was used to create that effect, I’ll contact the author about that now.
As you can appreciate the world of web design is incredibly fast moving so if there is anything else that you (or anyone) have noticed isn’t working, in any browser, we’d love to hear what it is so we can get fixes out as soon as possible. The address to use for letting us know is support(a)softpress.com.
I have a fix for this problem, but I would appreciate some testing from those of you who have the problem before I release it into the wild. Please contact me at waltd[at]wdstudio.com for the details.
The Action has changed significantly to fix this problem, and you will need to re-build your pages as a result. In the process, though, I found and fixed several other bugs that were reported elsewhere.
