TIWMemo displayed with wrong margins

For example the following settings:

IWMemo.Align := alTop;
IWMemo.AlignWithMargins := True;
IWMemo.Margins.Left := 16;
IWMemo.Margins.Right := 16;

In design mode it works correctly.

At runtime the memo will displayed  with left margin 0 and right margin 32!


BTW:
The cursor is not visible if no text has been entered yet.

Version 15.6.0

Please correct these bugs.

Thanks!
