Hangs till out memory
I think this has been around for a while
Hi Alex,
Sorry about that. 
As far as I know, that bug was new to version 15.1
It is fixed in the current beta. The beta will copy settings from your 15.1 installation, and then after that each version will maintain its own copy of settings.
