I am amazed that there is this big a difference.
I am a bit concerned about speed as the real code will have to do quit a bit of db querying. In design mode I need to get the corresponding rack item db row for each bottle (e.g. 200 for the single stack and 391 for the double stack), the sizes of these racks will obviously be user definable and can go way higher then this. In the viewer this will be even worse as for each rack item db row I have to get the related rows if a bottle is stored in this location to be able to display such things as wine name, vintage, image etc etc. >> Figured out how to move (by copy/pasting :)) the "frame" of a rack, >> but I am unsure on how to move the "children" i.e. the bottles >> (circles).
