Looks good !
I never found out what caused the changes I made to make the app bomb - and probably not never will since I just pasted your newer version over the top!
One thing I'd do for sure is to not nest the HolePattern and Hole classes within the window class - doesn't make for re-usability.
I'd also proably do what I suggested before: Use a sub-classed canvas and move the methods and properties controlling the drawing of HolePatterns to it thus leaving very little in the window itself except the UI controls which would then just need to be hooked up to the canvas properties.
Few other things (that I'm sure you are aware of) like using a generic method taking a HolePattern parameter to replace DrawHoles() and DrawHolePattern2()
Might be nice to zoom the canvas if the user resizes the window......
I must admit that copying and pasting the code and running the app made me wonder how big a message it would have taken it you'd written this in VFP <g>

Viv
