It gets even worse. When I am working on multiple files, the .tif files get overwritten by the new import. file1.sla uses USER-1.tif through USER-5.tif, file2.sla uses USER-1.tif through USER-3.tif
Now if I ope up file1.sla, several images get mixed up with the file2.sla .tif files. I'm totally confused and frustrated.
