The class "Cursor" has class variables containing the forms for the different cursors. You can change them with Cursor classPool at: #MoveCursor put: cursor. In general you can set it to any form like this: |form cursor| form := (Form extent: 23@23 depth: 32 fromArray: #( 0 0 0 0 0 0 0 ... 0 0) "the array representing the form" offset: 0@0). cursor := Cursor extent: 23@23 depth: 32. cursor offset: -12 @ -12. cursor bits: form bits. Cursor classPool at: #MoveCursor put: cursor. "the cursor you may want to change" cursor beCursor If in Pharo 2.0 just open Tools -> Configuration Browser. There you will find a configuration for "Vista Cursor" which should give you an example. Have fun T.
