I've installed the latest version (v3.2, 64 bits) on a Windows 10 enterprise operating system. When cloning or adding a new layer, the application crashes.
The main Golly process appears as "Suspended" in the account system in the Windows process explorer (sysinternals), and hence cannot be killed.
This error is quite common with "older" applications. It is probably the consequence of a tighter memory access policy under W10, i.e. a copy operation writing outside a preallocated memory zone. Uprounding errors due to the buffer size being a multiple of 64 bits could be a possible candidate.
Please try turning off grid lines (untick Show Grid Lines in the View menu) and then add/clone a new layer. Does that avoid the crash? We recently fixed a similar-sounding crash on a Linux system with an NVIDIA card, so if it's the same problem on your system then the upcoming 3.3 release should fix it.
