Sprite Ingrid Stand right: 16x16 2frames monochrome non-masked (as in page 173 of Duefectu's book for Boriel students)

Supposedly buttons undo/redo (lefthandside of button "Clear active patterns) are certainly inactive: dark grey background, no message appears when mouse arrow is on buttons, they do nothing when pushed.

Buttons cut/copy ("Cut active patterns to clipboard" and "Copy active patterns to clipboard") block the program when pushed: control is lost and nothing can be done.

Same here with 1.6 versions (beta 5 and 6.3) about cut/copy buttons.
