I'm still noticing an occasional crash in Toolkit, it seems to be related to reporting of Group Levels and the Application Log.. If you're finding the same thing, I suggest you turn off Live Group Levels and the Application Log unless you need them, they can be turned off by selecting the File Menu then Preferences then unchecking "Live Group Levels". Turn them on as required for identifying units/groups or diagnosing issues on the Network. My apologies for this, I'm sifting through the source code at the moment and have identified a couple of weaknesses with it that might explain it.
