I do this test:
The form has keypreview enabled;
in keypress:
Caption:=ActiveControl.ClassName;in the form, i put 1 panel with 1 edit, 1 combobox and another edit.
When i run and press tab after the combobox, the focus goes to the panel, and not to the last edit.
I Use Lazarus 9.30.2 in Kubuntu 12.04
It's works in the new version?
