Exception when rolling instruments

[NJA_MC]

BETA5: I go this error when starting NT8. I am not trying to roll instruments, this seems to cause my ES 12-15 Tick Chart to freeze as well. There is nothing under "Databases" that seem to want to roll, so this might be an old request still trying to execute?

2015-09-21 13:40:15:447 Exception when rolling instruments: Unable to cast object of type 'NinjaTrader.Gui.NinjaScript.Editor.ScriptItem' to type 'System.Windows.Controls.TabItem'.

EDIT: It may not be related tot he hang... More on that later...

Hi NJA_MC,

Can you attach your trace file for today to a reply on this thread? I'd like to look at it and see if that gives us any idea of why this rollover request is happening.

This was the crash I got when attempting to roll in addition to not being able to connect to Rithmic with B5
