Brethren

This is quite simple, this Tk based form displays directory tree structure of any given drive letter. The way it works is by typing in the drive letter in the entry box at the top and the directory tree will be displayed in a box underneath, by default the script will pick drive C to start off with. This bit works fine however, when I change to another drive, an error occurs (Tk based error implying that the script did not understand the instruction “$tk{dir_tree}->delete('0.1','end');” which is part of the sub OnNewPath. And all it was meant to do is to delete what ever is displayed in the DireTree box and replace it with DirTree structre of the drive letter that was inserted in the entry box.

Any pointers or advice is highly appreciated....
