I used the outer glow effect on some of my objects until it suddenly stopped to work. I reset my preferences and tried other different solutions until I found out
that the outer glowing effect stops working as soon as you overlay such an object with another one. If you just partially overlap these two objects the part which
does not overlap still shows a outer glowing effect. Is that a normal behaviour? that was also the reason why the glowing effect suddenly disappeared. I added
a coloured rectangle as a background... any ideas?
Here is a extreme example and it seems that the effect is quite heavily suppressed even though the straight line is brought to the front!! It is not behind the gray shaded rectangle
