Now I do not have cog on my machine because it gets on my nerves to also bind as a default vm (Probably a mac config files but I'm waiting for an official stable version).

[Pharo-project] Bigger cursor

by Torsten Bergmann

Works for me on Windows with Pharo 1.2/1.3 and Standard as well as Cog VM. Haven tried on Linux or other platforms. Since it's code from OLPC I guess it should work also on non-windows platforms - but maybe the VM code was not integrated. You may ask on vm-dev list.
