"Unable to create SftTree control"
I am upgrading a project from Compact Control Builder AC 800m Version 5.0.1/2 to 5.1.1-1. The upgrade itself went fine, but now whenever I open a program I get this message "Unable to create SftTree control!" and I can't navigate in my code blocks using the Structure View.
I get this message everytime I either open a program or open/switch to another code block. And it seems lite Control Builder is unable to generate a Structure View for my project.
What is causing this? Can I fix it?
