Hi All,
Coming back to this issue, done some other test and it gets more confusing.
I have updated to latest version of Trunk
Lazarus 2.1.0 r63745 FPC 3.3.1 x86_64-win64-win32/win64
If I set the anchors on the label so that the label auto sizes to form size and positions itself to the right of the label, the label moves as expected, but the form re-size event is not fired, if i use call the form re-size code in the label re-size event the form event is called as expected.
I added a checkbox to the sample so you can turn this behaviour on/off. This itself I notice another bug, I change the checkbox font color to white in the ide, but the ide still shows the checkbox font as black, if you run then the font color is showmn correct.
