1. Create a WinXP bottle
2. Open the Winecfg file from the Manager
3. Ensure 'Emulate a Virtual Desktop' in the Graphics tab is checked and then enter a desktop size to your preference. (The other checkboxes have little if any effect on running the program)
4. Close the Winecfg window and do a full HardDisk install of the WTLib05. (Doing an install that requires the insertion of the CDRom for viewing publications will not work - Have the complete library installed to your HardDrive
5. Choose the defaults for file location.
6. Once installed, which should happen without any complications, open the WTLib from the CrossOver menu bar.
7. When the main page has opened click the 'maximize' button and then adjust the viewer panels in each category to suit your needs (They're a bit small to start off with) and you're good to go.
