I added a folder to a drive and dropped some media into it, then went to AMA thru the source browser. The drive already had a folder in it with footage that I had AMA'd to previously during this session. After adding the new folder with new media, the source browser will not see that new folder.
The only way I can get that folder to be seen is to quit out of MC and the relaunch. There doesnt seem to be an option to refresh the source folder to recognize anything new.
