Continuous stream of "Error loading" message in up

[VistaViewer]

I am running WhiteCap in IE 7.0 under Vista Ultimate X64

I get a continuous stream of error message strings in the upper left corner of the didplay. They look like all this:

Error loading WaveShape: Blue for Mirium.txt (-55015)
Error loading WaveShape: Sketch.txt (-55015)
Error loading ColorSchemes: Any Hue.txt (-55015)

And on and on it goes... Only the .txt file name changes.

Can anyone suggest what I might do to fix this?

Thanks in advance.
