Hi. No notable improvement removing the 4GB stick unfortunately - there is possibly a small improvement since upgrading to 12.8.3 so will see how that goes. One suggestion was to downgrade to 12.4 (possibly incompatible with WIN10) but I'd prefer not to go backwards if at all possible since I have paid to have the latest version. Will use the system in the new year and see how it goes. thanks for your suggestions so far.
