Plotting within foreach loop

I am running into a problem when I try plotting a set of waveforms from within a foreach loop (code snipet included below). When plot function is executed, Virtuoso Visualization and Analysis Wavefom Graph XL is opened and three waveforms are plotted. However, the plots are all identical being the same as the first waveform to be plotted (waveform[0]). When I plot each waveform individually without a foreach loop (i.e. three separate plot statements), all three plots are generated correctly. I also verified that the waveforms are indeed different by writing them into an output file.

Is there some reason why plotting from within a foreach loop not work? I am using IC6.1.5

Thanks for the help.

declare( waveform[3] )

;foreach loop saving corner simulation waveform data into waveform[n] for n=0,1,2

indexList = list( 0 1 2 )
win = newWindow()foreach( (ind) indexList

     currentWindow( win )
     plot( waveform[ind] )

)
