When i add one component (button, label, etc..) and double click to add "onclik" or some other event Lazarus show an error message "Error TDefaultComponentEditor . Unit not found"
in code is selected the last added unit like "StdCtrls".
The program compiles but i can't add functions to the events.
I'm using SVN 0.9.29 2010-10-06 FPC 2.4.3 SVN 27585
