If I have no buffers/windows open and I try to open a file using load-from-project I get Invalid object handle file=tbfilelist.ex offset=4491
Stack:
Invalid object handle
tbfilelist.ex 4491 tbfilelist:open_selected_files() p_window_id: 154 (invalid)
tbfilelist.ex 4223 _tbfilelist_form.ctl_file_list.on_change(16, 491) p_window_id: 154 (invalid)
treeview.ex 1083 _ul2_tree.enter() p_window_id: 154 (invalid)
If I already have a file open, then opening using load-from-project works fine.
Since I've just been installing the betas in new directories and using them, it's possible that this doesn't happen on a clean install.
