@halroach Hi, I'm new to Flex tools and finding the same issue. 6 years on I am just wondering if there is any improved approaches or do I need to follow this one? What I am wondering is if there is a way to have adjacent flex windows (critical for my project, many adjacent windows) and maintain the point of the flex tools in being able to adjust the dynamic aspects later. This workflow seems to mean I can no longer adjust the settings the windows individually? thanks in advance for any help! Luke
