0. have QTTabBar installed, and an explorer window open, with its tree view.
1. click a folder in the tree view, make sure it contains multiple files
2. move your mouse cursor to the file list window, do not click on anything,
3. now drag your mouse to select.
4. things to note: you're making a "shadow selection", the parent folder in the left tree view is still selected and highlighted, and on the right the selected items are in a gray selection rectangle.
5. now if you press shift+delete key combination, mostly u mean to delete the selected files, then you'll be surprised badly, the parent folder in the left tree view is still highlighted, then that will be object to be deleted!!!!!!!!!!!!!
when I just found the bug, I thought I was smart enough to avoid it by first click any item in the file list window, to remove the highlighting from the parent folder, now the fact is that I'm not that smart, but stupid actually, after lost many important stuff, now hurt badly by this "shadow selection", finally I learn the lesson and uninstalled QTTabBar immediately with no hesitate, without any mercy for the lost of the pretty grd-lines and tabs, good bye, and go to h**l.
