1. Select "Cleaner" or "Registry".
2. Try to resize the tree window by moving the splitter.

Please include the Graphics Controller information

Intel 946GZ Express Chipset Family, driver version 6.14.10.4926

The driver appears to be down level:
Intel® Graphics Media Accelerator Driver for Windows* XP (exe) (20476KB) 14.36.4.5002 10/24/2008

* Driver Revision: Production Version 14.32.4
* Package: 45357
*
* Graphics: 6.14.10.4926
* HDMI Audio: 5.10.0.1030
