moving a process flow within a project

[LiamRowan]

A colleague can left click on a process flow name in a project tree and then drag the process flow to a different location in the tree.  When I try to do this I get the universal "not allowed" sign--a circle with a line through it.  We both are using the same version of SAS (7.12 HF4 64 bit).  We both use Win 10.  Any ideas on how I might be able to get this function to work for me?

Thanks

Just checking...  If you click the left mouse on say process flow A and then drag process flow A over process flow B do both process flows get highlighted in the tree?

Yes! And when I release the mouse over the highlighted process flow B, process flow A does move to the spot preceding A. Lord, it was so simple. Thanks so much!!!!
