I also just updated to MC20 after using MC19 for about 1 year now.
However, I must have missed the memo to uninstall MC19 because I also now have two versions installed on my PC.
In fact, MC20 appears to be a fresh install with none of my settings for MC19. Did I do something wrong?
When should MC19 be uninstalled? Is there some way of saving the settings in MC19 that can be restored to MC20?
Thanks,
Herb...
