I found this on the web, but it didn't work on my PC... Maybe on yours it will...?

finaly found it. We had the same problem here with users
draging folders by mistake. You can set the drag and drop or
copy and paste files confirmation prompt
1802 = Drag and drop or copy and paste files
Note: Unless stated otherwise, each DWORD value is equal to zero, one, or three. Typically, a setting of zero sets a specific action as permitted, a setting of one causes a prompt to appear, and a setting of three does not allow the specific action.
Locally
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Internet Settings\Zones\0]
"1802"=dword:00000001
AND on the intranet:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Internet Settings\Zones\1]
"1802"=dword:00000001
