Sorry, we are still not sure what you mean.
When you say “editor” which editor do you mean?
- the UE4 editor
- the SkookumIDE
- Windows File explorer
Where in said editor are you dragging from and to specifically?
Can you please give a specific example? Even if it is particular to your project that is okay. We just need some idea of what you are talking about.
SkookumIDE can drag around tabs and windows, though that seems fine.
We tried moving asset files in the UE4 editor content browser and that seems fine. Moving objects in the view panes also seem fine.
Moving script files and folders with the Windows File explorer has the SkookumIDE pick up the changes and reflected in its Classes widget. Seems to work with whole classes or single routines.
Either we cannot reproduce what you are saying or we do not understand what it is that you are describing.
