Did not help. Thought it might have something to do with a Serial.read() used to input register values on the fly but I took that out and created simple loops to do the fades also. It made no difference. My goal was to simultaneously fade in/out a chain of at least 2 SBs between about 9 or 10 set color mixes, with a different color mix on each SB based on serial input. The serial input would provide two fresh sets of RGB register values on each read to control the color mix and fades.

Not using the shiftbrite.h
Not using the shiftbrite.h library since others reported problems.
Tried this an called it after registers are all set:
void SetLatch() {
delayMicroseconds(15);
digitalWrite(enablepin,HIGH);
digitalWrite(latchpin,HIGH);
delayMicroseconds(15);
digitalWrite(enablepin,LOW);
digitalWrite(latchpin,LOW);
}
