Nest Trader 3.16 is bad. Crashes a lot.
This has to do with Plus Charts, so avoid going to Menu > Nest Plus > *****
There seems to be an issue with Nest Plus not starting at "Startup" even though set in Plugin Manager.
Simple way is to just login to NEST3.16, Go to MW, select scrip and hit <Shift+P> or use Menu and open nest plus charts. also, Shift+H for historical.
If Nest Plus is running, respective chart will open otherwise the Nest Plus Login Window will appear.
If password is blank, enter the correct password.
Fiddling via "Launch Plus" or "Logout/Login" and other stuff in the Menu of NEST causes it to die completely without any Error messages.
I can reproduce this consistently on more than one m/c.
