Actually you can use the flattening action, if the corners (maximum 2) that need to be corrected are ''above'' flat level and it takes no more than 14 seconds.<br>
If only one corner is 2 steps from being flat, you can use the flattening action here too (19 seconds). --[[User:Helge|Helge]] 16:46, 13 June 2006 (CDT)
