If I open into a contact sheet a folder having no images but only folders in it no images appear (as it should). But if I try to open the same folder and its subfolders Replacing current contact sheet I receive an error message saying:
"One or more of the folders in the subfolder scan are already open as a contact sheet. Operation cancelled."
By my understanding this should not work this way. Instead the folder and subfolders I selected should in deed replace the currently open stuff (that in most of my cases means an ampty contact sheet).
