This may look like a minor point release (from v.1.1.10), but...
I was in my Overloud account specifically to check for a REmatrix update (I bought it on that excellent group buy a couple of months back), since it had crashed SONAR a couple of times. From the Release Notes:
1.1.10 -> 1.1.11
----------------
- Fixed an issue on Windows where scrolling a list under certain circumstances could cause a crash
- Fixed a condition that caused excessive CPU usage or spikes in some circumstances
- Fixed a condition that prevented authorization or evaluation on some Windows laptops
Fix #1 sure sounds like what happened to me.
