The issue is not the browser but the security limitation imposed upon Javascript itself (which XBMControl is written in).

As a test case please try running chrome in the mode suggested in my previous post. If it works then the issue is the security restrictions in javascript.

Yes, Chrome worked when security is disabled... but this is not a solution, it just shows that we need to find a better way to do it Can you see how Maraschino does it since it works perfectly with Maraschino in all browsers, without disabling security?

1 problem: Drag and drop, how ya gonna do that... on a tablet / phone

sliding (to the right in this case) and/or adding buttons to each line (less elegant) like Maraschino does for mouse hovers.

Maraschino has its own backend, and therefore not restricted to the javascript limits, since the Maraschino server calls the urls, not the browser.

Don't know if kabooga uses jquery if that's the case: http://touchpunch.furf.com/
