I just installed Beta 13. Right after I first run SGP, I click on “Open Sequence” folder icon at upper left, it crashes consistently. If I use “File->Open Sequence” pull down menu, it’s fine.
At first I installed Beta 13 over Beta 11 and then uninstalled Beta 13 and re-installed Beta 13 and same issue remains.
I am using Windows 8.1 HP laptop with i5 CPU.
