Are attached logs from my other laptop, latest version, any better?
I only skimmed through the StreamFab.log because you have many sessions in it. For the most part all the sessions look to be complete. You start off using SF version 6.1.1.3 back in July and end with version 6.1.5.2 from today. In between there are some 6.1.4.7 sessions.
In general, if you are going to be reporting a problem, it is probably best to delete the existing StreamFab.log before you start a session. It makes it easier for the developer to track down the problem without having to hunt for it. But on the other hand, it is hard enough trying to get someone to attach a StreamFab.log without asking them whenever they report a problem, so I guess we should be grateful for whatever we can get.
