Dear Bruce, In October last year (October 22) I reported a problem in Demeter. I couldn't open Artemis or Athena. The only thing happening was two screens popping up quickly before disappearing. You replied that you had never seen this problem before. Since then I have used Demeter in Ubuntu. Now, first I have to be honest. I haven't read all the threads posted about windows problems with Demeter lately, so I do apologize if you have this solution already posted somewhere. I have been looking into this problem today on my computer again as I found it very frustrating switching between two OS. So, I checked my local environment settings and for some reason there was a whole list of crappy paths accumulated under PATHS. Don't ask me why, I have no idea how this happened. I deleted, after uninstalling Demeter first, everything related to strawberry in PATHS. I also deleted strawberry in C:\strawberry. Then I reinstalled Demeter and everything seems to work fine. Maybe this will be helpful for some people experiencing a similar problem. Best wishes, Arjen ir. A.
