I'm searching for the solution at the moment, if I find the issue I'll try to create a patch for you.
1. If you have a licensed source code you will have the download available in the download section (In the future please post the issues in your Priority support forum we will address them faster
2. Here is the unofficial change log
Changelog for MonoX 4.5.2915 (released on 2011-10-01):
MonoX mobile: a complete set of new mobile Web parts and pages based on the jQuery mobile framework
Full support for the WYSIWYG editor mode - page style is reflected to all elements in the HTML editor
Totally redesigned Web part catalog, introducing performance improvements and support for drag-and-drop in all major browsers
Enhancements of the Web part zones, using the "tableless" Web part zone as the default option to optimize the HTML code rendered by MonoX
Fixed AutoEventWireup infrastructure

Fixed localization in file upload parts
3. I'll provide you with the patch as an assembly and as a code patch that you can apply to a source code.
