Hi Conrad,
If you have posted a list to a folder and then want to delete the list,
you should do;
l->Delete();
delete l;
The first statement will take care of removing the entries in the list
from the browser automatically. Executing only the second statement is not
sufficient.
There is however still a problem with the browser in some complex
combinations when the objects hierachy is in the left pane and the right
pane of the browser. This problem will be fixed soon in CVS.
