I am trying to use Lazarus IDE, but I’m encountering bugs, crashes and weird behaviour.

1. I try to rename a panel in the GUI editor, and I get this error. If I edit the uses line and change the order of the units, the error simply changes to complaining about another unit instead. The project will compile, but the visual designer throws errors:

2. Also, the ChildSizing property on one of my panels no longer has any effect: The child controls are not sized or affected by the setting. What could cause this? I have tried clearing the child controls’ anchors.
