Hi,
I have full working application with the ext.net.dll version 1.0.3960.37522.
Once I tried to upgrade it to 1.3.0.1840 application stopped recognize stores in the page and generate javascript errors.
I tried to create brand new project by moving my files and new ext.net.dll into new website. Still have the same problem.
Once I put old dlls back, everything is working.

Please help.
