Can move only one file at a time within same folder or get error msg

I often need to reorganise files and sub-folders within the same main folder, for example, move folder from sub-folder named documents to sub-folder named photos. However Explorer in Windows 7 Professional will only allow me to move one folder at a time. When I try to move a second folder I get the message that I can't as the file or folder is open! Of course it is - I'm trying to move files within it! I'm reduced to sneaking up on it every few minutes. This can't be right, please help

Hi - I'm trying both and still get same message. Have recently moved from Windows XP and wasn't an issue at all there
