i did try with default. AND even tried default with NO selections.

it was slow with no selections, dog slow with selections.

out of curiosity, try adding pocket sudoku to your build, then open it and set the level to "very hard" then click "new" to generate a new very hard puzzle. under my old build, it would finish this task in about 5 - 15 seconds. since this new kitchen, no combination of build options is capable of finishing that task at all. you will get a "generating" message forever.
