Hi David - Maybe something to do with using a repeat loop within the
mouseMove handler. Here's a script for a split pane (horizonal split)
display out of a stack of mine that does something similar (ignore the
internal details of the mouseDown handler) and uses a flag to track the
status of the mouse rather than a repeat loop.
HTH,
Terry...
local pDown, pYoffset
on mouseEnter
lock cursor
set the cursor to 8113
end mouseEnter
on mouseLeave
put false into pDown
unlock cursor
end mouseLeave
on mouseDown
put true into pDown
put the mouseV -(the top of me) into pYoffset
end mouseDown
on mouseUp
put false into pDown
end mouseUp
on mouseRelease
put false into pDown
end mouseRelease
on mouseMove x,y
if pDown then
lock screen
set the top of me to min(540,max(y-pYoffset,203))
set the top of grp "messageDetails" to the bottom of me -2
put the rect of fld "message" into tRect
put 701 into item 4 of tRect
set the rect of fld "message" to tRect
put the rect of grp "announcements_DG" into tRect
put the top of me +1 into item 4 of tRect
set the rect of grp "announcements_DG" to tRect
unlock screen
end if
end mouseMove
