Use MouseLine() and still edit the same field?

Hi Mark - you probably want to use a mouseMove handler rather than
mouseWithin. Try starting off with something simple like this...

on mouseMove
    put word 2 of the mouseLine into n
    set the textColor of line 1 to -1 of me to empty
    set the textColor of line n of me to blue
end mouseMove

HTH,

Terry...
