We released a new version of slideshow with fixing Safari fade effect issue.
We have been notified that slideshow does not show images in Safari browser so tried to find and fix the issue.
I noticed this issue appears only on Safari browser when fade effect is selected.
An overflow:hidden attribute for "#mss-slider_[MODULEID]" class in template.css file was making this problem.
To fix the issue you can get the latest version from slideshow page at markitmodules.com and update your module or open template.css file and at line 3 remove "overflow:hiddne".
