Found the bug.
My project consists of a large number of TFrames, placed on pages of a giant TsPageControl. Some of these frames may show pupup windows. If these windows close, they set the Action to caFree and set there form variable to nil.
One of the popup windows did not set the form variable to nil. Causing the problem.
I still think it’s a bug in AC. Setting Action to caFree should be enough.
Hello!
The package doesn’t use these variables, they are not accessible in units of the package.
If I understand you correctly.
Can you help me to repeat the error, please? Is it possible in a separate demo-app?
