Hello

I installed the new version 2025.44 and noticed some problems with my program.

After investigation, i create a small demo program, see attachment.

Compile it with v44, the start it and press the "view" button, then "hide". then you got a exceptions. I also got an exception, when i delete a Series at design time in the IDE.

Compile and run it with <=V43 it runs without any problems.

Delphi 12.3.1 Build the program with Win32 and Win64.

Hope this will be fixed.

Thanks in advanced
Gregor
