I was having this issue as well, whenever I would open a file open/save dialog box the program that called for the box would hang, fade to gray, hang for a few more seconds, then launch the box. Seems it was a tracker-indexer issue for me as well. I killed the tracker-indexer process and everything resumed back to normal.
