Trash bin never show filled
1. Every time I want to delete a file, it always ask me to write my password.
2. After I write my password, the file is vanished from Finder, sound "trash-ing", then the Trash icon on the Dock doesn't show filled.
3. It cause my internal drive almost full!
MacBook, Mac OS X (10.7.5), I used SSD Kingston Hyper-X 120 Gb
