Luckily the #overlay solution works, but it renders the showBackButton option useless, though.
It does, however, work for both the Flash and the Mobile Players so may be a suitable (and universal) workaround.
Do you plan to implement the back button in the mobile version of SV?
I do not know what features are likely to be added in future versions but the please post feature requests in this forum so that they are not overlooked.
And, is there any documentation of what is not working in the mobile version of SV?
The only options available for the Mobile Player can be found here.
The other options found on the SimpleViewer-Pro Config Options page (other than the 'title' and a few of the Embed Options, eg. backgroundColor, galleryWidth, galleryHeight) are for the Flash Player only.
