uhm... 

I was trying to make OpenCV working on Processing 1.5.1 and followed  some intruction in the forum to add a PATH to the system's variables and I'm afraid that I did something else too, because after adding the path to openCV\bin if I try to launch some example from the video library i get this error: 

UnsastifiedLinkError: no QTJava in java.library.path 

But I have as CLASSPATH variable " .;C:\Program Files\Java\jre6\lib\ext\QTJava.zip; " 

and as 

QTJAVA variable " C:\Program Files\Java\jre6\lib\ext\QTJava.zip " 

anyway the video library for Processing 2.0a1 still works... 

what to do?

thanks!
