[REBOL] IRSee.r now with ENCRYPTED white board.

From: depotcity::telus::net at: 9-May-2001 2:09

IRSee now has an "Encrypted" white board. Available at the LFReD rebsite (may require a reload) or below. Special thanks to Mr. Kamp for the canvas.r pane. In theory, the "L" load button on the whiteboard canvas should start a loop that continuously refreshes the drawing, but it doesn't. Requires hitting the "L" button again and again. Any ideas?
