Right button menu not available in the empty zone of the collection list
If a collection list of item is not long enough to fill the windows, clicking on the right button in the empty zone after the end of the list has no effect. It could display the menu to change the type of list (text, images).
When the list is in text mode, there's an unhandled exception
*** Can't call method "to_string" on an undefined value at C:\My Program Files\GCstar_Git\gcstar\gcstar\lib\gcstar/GCItemsLists/GCTextLists.pm line 360.```
