I understand why during opening of the window tt gets stuck - because I called for EditCellAt during a method (Fill) which fills the Listbox and then gets called again in CellGotFocus. The last call for some reason then goes to CellLostFocus. It then cycles through Got and Lost.
What I don’t understand is why it gets stuck.
Edit: If I remove only the call during Fill. it still gets stuck.
If I leave in that call, but remove the call in CellGotFocus, I have no problems at all.
