@brianolive - I have had a few recent crashes, one of them involved a massive texture which I tried to build - I think it was 512 x 48 x 512 x 48. What memory intensive routines/command are you using? Also are you cleaning up with collectgarbage() ?
The other incident occurred after running some file/text handling the starting another project and pasting copied code straight into draw - on running Codea crashed but reset after closing Codea manually (reported on March 17) in Codea 3.1.1 (280) thread.
Oh, the other issue with wrong project opening after a closure has been reported. It seems to be down to project shuffling after project closure - when the latest project run house to the top of the pile - all others shuffle down and you run one of the ones next to the one you was targeting. You can often see the shuffling of project icons.
