It seems I have lazarus list mail problems, am getting only some stuff) Can you please elaborate more on the LookupRoot property? What do I need to set it? The first "item" in the list (because in my case the propeditor is a list of things) and in case there's none, to nil? I did everything else and currently am getting AV on any operation in the property form. It also doesn't seem to change the OI right now (doesn't empty it either tho, last thing remains selected). I'll try and debug the thing further tomorrow. Thanks,
