I mention this issue not because it's important, but because it involves pen up/down logic and I just want to check that there is no larger problem:

• When the pen is plotting at a distance from the document border - for example when doing a spiral-text plot - and
• if user presses the "pause" EBB button, and
• user then selects "Resume" tab, and
• user checks "Cancel and return home only"
  then
• the self.bPenIsUp variable is uninitialized, and therefore
• plotLineAndTime() will ignore user's x-wrap selection, and
• will perform as many egg revolutions, at pen down speed, as it takes to get back home.

A possible fix is shown in the attached image, but it may be that this is but a bandaid for a larger problem? or a different problem?? Dunno, but just wanted to bring it up.
