Articulate Storyline Freezing

Having a similar issue to what is reported above. My team recently migrated from SL1 to SL2 (update 5) and we're all having this "freezing" issue with the application itself randomly with no pattern we've been able to detect. Same as described above, all other apps and Windows are alive and working normally. This morning SL2 started doing it immediately upon launch, nothing within the SL2 interface was clickable except minimize, maximize, or close in the upper right. So I closed it, waited a bit, restarted, then it wouldn't allow me to resize the UI using the mouse or the max/min window functions. Instead the application window would just jump around the screen. Close, wait, reopen and for the moment it seems to be behaving but I expect that to be short lived based on our experience to date. There's often enough challenges making content do what you want it to do in Storyline without also having to fight with the development tool itself.
