Black grid on tab control? Is this a bug?

[Exaurdon]

I have run into what appears to be a labview bug. This is the second time I have encountered this problem, both times it has been on the tab control.

I was just modifying some block diagrams, and when I went back to the front panel, I get a grid of thick black lines. Also, if you move control around, they leave 'artifacts' behind. I tried closing the app, ect, assuming it was just a screen redraw problem, but it didn't go away, so I tried copying it onto another computer, and I got the same problem on anotehr computer.

Everything seems to be functioning, it is just a display problem. Has anyone had experience with this? Also, if you download this VI, and cannot see the black lines on the front panel, let me know.
The VI is ElectrodeEditor2.vi. You will need the database connectivity toolkit to open it.

Thanks,

I see the black lines as well. I was also able to remove them. One way to remove them was to replace the standard tab control with the dialog tab control. The other way was to shrink the size of the tab control (it's dozens of screen sizes wide) until it was something only a little bit bigger than the controls it had on it and it was no longer on top of the error clusters. It does seem like a bug but I don't know if it was the result of the enormous size of the control or that plus the controls that were behind the tab.

Ok, once I shrink the control size down, things seem to be back to normal. I'm not sure what caused the control to grow to such a giant size in the first place... anyway, apparently Labview has some bugrelated to drawing that large of a front panel or control.

Thanks for your time.
