v1.8.9 bright 8 does not work (*solved*)

[Eqx]

Hello Boriel,
I found a problem wih bright 8
I'm coding some routines for a game and I need use bright 8 to draw four lines on a square with attributes: ink 2 and bright 1
I set paper 8, ink 8 and bright 8 to draw lines in this zone but zxbasic changes the brightness to zero and seems doesn't works.

Thanks

Code:

ink 2: bright 1
plot 117,154:
draw 0,-8: draw 1,0: draw 0,-5: draw -1,0: draw 0,-8: draw 8,0: draw 0,1: draw 5,0: draw 0,-1: draw 8,0: draw 0,8:
draw -1,0: draw 0,5: draw 1,0: draw 0,8: draw -8,0: draw 0,-1: draw -5,0: draw 0,1: draw -8,0

do

.....

if IN 32766 = 190 go sub fire

print paper 6;over 1; INK 0;AT 5,15;"  ";AT 6,15;"  "

loop

fire:

ink 8: paper 8: bright 8: over 1
for n=1 TO 2
    plot 0,191:draw 126,-47
    plot 255,191:draw -126,-47
    plot 80,75: draw 48,69
    plot 175,75:draw -48,69
next n

over 0

return
