*Catalyst 9.8 & 9.9: These driver versions may cause some issues with Wurm for some ATI cards
*Catalyst 9.10 & 9.11: These are known to resolve some issues with 9.8 & 9.9. You may find that 9.10 will not work and that 9.11 will - or vice versa!
Catalyst driver version numbering system may have changed at this point ..
Full uninstall and subsequent install of the 11th May 2011 drivers may correct the problem with Wurm not exiting properly, ie it keeps its memory allocation and continues to be listed in the task manager.
