I noticed a strange behaviour of the text shown by the draw command.
If I issue the following two commands after loading PDB entry '1DEH',
everything seems to work fine:
draw border1 PERP 150 PLANE (5:A.CA) (6:A.CA) "Exon 1/2";
draw border2 PERP 150 PLANE (7:A.CA) (8:A.CA) "Exon 2/3";
The planes appear in the right places and also the labelling text. I can
switch each one on and off (e.g.: 'draw border1 on' and 'draw border1
off') and everything looks fine.
But if I add translucent to the modifier list, the labelling texts get
mixed up:
draw border1 PERP 150 PLANE (5:A.CA) (6:A.CA) "Exon 1/2" translucent;
draw border2 PERP 150 PLANE (7:A.CA) (8:A.CA) "Exon 2/3" translucent;
The text of 'border2' appears at the same coordinates as the text of
'border1'.
If I then switch off 'border1', the text of 'border1' disappears and the
text of 'border2' remains at the wrong position.
If I know switch 'border1' on again, both texts appear now at the
coordinates for 'border2' (and the text of 'border2' disappears at the
coordinates for 'border1').
The same happens if I add the 'translucent' in a second command without
redefining the coordinates and the text: 'draw border1 translucent'.

Rolf
