grows and grows... it seems the blk is not clearing? That's right. You're not 'clear-ing the block, merely assigning it to a block. See: button "Clear" [blk: [] d: 0 y/text: "00:00:00" show y ] Note that the block! that 'blk is referring to, isn't 'clear-ed at all. To remove all the values in 'blk, do: clear blk Note that in Rebol, the words: blk: [] mean set the word 'blk to the value []. In otherwords, in your program, here: blk: [] d: the block between "blk:" and " d: " is where the value of the block is. The block is not "in" 'blk. It's literally in your script. Rebol words act like pointers or references do in other languages. Andrew Martin ICQ: 26227169
