Xbee analog inputs

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Trying to read some analog valeu with the getAnalog() function

What is the expected output? What do you see instead?
The output that appears is like this example.

Analog (AI0) is 419
Analog (AI1) is 419
Analog (AI2) is 419
Analog (AI3) is 419
Analog (AI4) is 993
Analog (AI5) is 419

Notice that AI0 and AI4 are the pins that i need to read, but the value of pin 
0 is replicated to the other pins. Also, all values on pin 4 start to appear on 
pin 0 readings. I'm getting 19 samples per packet, and on the third sample, the 
value of pin 0 is equal to the value of pin 4 on the first sample, like this:

Sample 1:
Analog (AI0) is 419
Analog (AI1) is 419
Analog (AI2) is 419
Analog (AI3) is 419
Analog (AI4) is 993
Analog (AI5) is 419
Sample 2:
Analog (AI0) is 10
Analog (AI1) is 10
Analog (AI2) is 10
Analog (AI3) is 10
Analog (AI4) is 993
Analog (AI5) is 10
Sample 3:
Analog (AI0) is 993
Analog (AI1) is 993
Analog (AI2) is 993
Analog (AI3) is 993
Analog (AI4) is 32
Analog (AI5) is 993

What version of the product are you using? On what operating system?
Arduino 1.0 on windows 7

Please provide any additional information below.
I'm using the libelium Xbee shield, i think it is or was the official xbee 
shield. Is there any issue about this shield and the Xbee library?

Thanks in advance
