yLimit doesn't work with awvPlotWaveform() if stripNumber is set

Greetings all,

Using version IC6.1.5.500.1

If I execute the following in the CIW,

• newWindow()
• awvPlotWaveform(awvGetCurrentWindow() (list <waveform>) )
• yLimit((list 1 2))

yLimit works fine.

But if I type the following in the CIW:

• newWindow()
• awvPlotWaveform(awvGetCurrentWindow() (list <waveform>) ?stripNumber (list 1))
• yLimit((list 1 2))

The yLimit fails with the message:

This command requires a valid object id.  No object with the id "" could be found.
No graph object selected.
No graph object selected.
nil

• newWindow()
• plot(<waveform> ?strip 1)
• yLimit((list 1 2))

 The yLimit command works fine. 

If I use the awvSetYLimit command, it works fine.

• newWindow()
• awvPlotWaveform(awvGetCurrentWindow() (list <waveform>) ?stripNumber (list 1))
• awvSetYLimit(awvGetCurrentWindow() 1 (list 1 2) ?stripNumber 1)

 Has anyone else encountered this issue?
