I have been trying to reposition manually a pdf file imported into the Research folder with no success.
It will happily move to a folder in the Research section, to the trash, or as a sub-whatever of a text file. It will not sit where I want it, though; just below three text files and before the first folder. It bounces back to the bottom of the list.
I am having similar problems repositioning other files (text). Folder behave themselves and go to where I command them .-(
UPDATE
Hah! I have finally managed it … but it took 10 minutes and the precision of a surgeon to position the file JUST so between the border of the two others. Is it possible to have other files “make way” for the insertion of a new file (as in Mac), or make a clear “insertion line”?
