#23 Disappearing HOLD

[Robert G Lee]

Clicking on a HOLD (---->) in a gloss field (sometimes) makes the
arrow disappear. Zoom out (or in) returns the arrow (selected and
red) but Minimize and Maximize does not. (This seems to happen
the first few times, then it doesn't, even in different segements with
holds)
