Thought it was better to take this discussion from twitter into the forum - So I'm having a weird issue using the MNTP in v6 of Umbraco - I filed a bug report here: http://issues.umbraco.org/issue/U4-1617
On twitter Lee Kelleher suggested that I deleted the uComponents.legacy.dll file and cleared my cookies.
This made the first yellow screen disappear...but then I get this baby...I have tried removing the property and adding it again...same result...
