Distro is Debian 503 using LXDE. Problem is that multiple files saved to a folder (in sequence, not as a batch) are not updating in realtime. App used was Iceweasel browser. Action was as follows: downloaded around three dozen large photos of jet aircraft, one at a time, in quick succession. The images saved successfully to a folder on the desktop but did not always show up in realtime in the open folder window. In order to find the phantom images, I'd have to either close the folder window and re-open or, hit the "sort order" arrows a few times at top of window (date, size or whatever) a few times for the downloaded files to appear.
