I have the following problem using UltimateEditorMVC control on tablets in my MVC application.   After clicking on the UltimateEditorMVC control to focus on it, I am able to type in anything I want.  After I typed something in, I highlight the text and click on the bold icon on the toolbar to bold the selected text.  Then, after I click on the UltimateEditorMVC control to type some additional text beneath the existing text, nothing gets entered into the control.  The only thing that I can do to fix this behaviour is to click on the spell-check icon on the toolbar to bring up the spell-check window.  After exiting the spell-check window, I can resume typing in the UltimateEditorMVC field.  I was able to recreate this issue on your sample site.  Let me know if you need any additional information or further details of the issue.  Thanks in advance!

We added a new property called UserAgentsToRenderTextArea and you can set its value to a pipe-delimited list of user agents to render the editor as text area (e.g. "ipad|iphone").

We released a new build and it is now reay to download on our website. Please download the latest version and try with it.
