With SAP GUI version 6.40 (R3 4.7) the GuiXT screen elements screen is always blank and the script directory is never found.

You can rectify this by installing the latest GuiXT version 2005 Q1 3 from our download page in www.synactive.com.
We had a couple of hiccups for 4.7 and sapgui 6.40. Our tests are now all OK for this configuration.
