Hello,
Found a BUG…
Rises EAccessViolation when gets message CM_WININICHANGE…
I notice this behavior while install update for Visual Studio.
Application was run under RAD Studio 10.3 (in Release config), and minimized,
get EAccessViolation many times… so it is stable.

it is here: sSkinProvider.pas (TsSkinProvider.NewWndProc())

        CM_WININICHANGE: begin
          OldWndProc(Message);
          if BorderForm <> nil then
            BorderForm.UpdateExBordersPos;
        end;

I can’t insert screenshots, so just attach.
bug4.png – Restart Application in Debug config, click on break when rises exception.
Hopes this can help to fix it.

Hello and thank you for screenshots!
Do you know steps for repeating the problem?
Can I repeat it somehow?

Need to send WM_WININICHANGE message…
And application must be minimized.
You can try the attached sample, to send broadcast WM_WININICHANGE

just now tried with ASkinDemo.exe, run, minimize, send WM_WININICHANGE
get exception

I just notice that AMegaDemo.exe compiled with AC 15.16 (which is not available yet),
and it doesn’t have this exception.

Thank you, this issue will be solved in the v15.16 (which will be available tomorrow =).
