BUG: Background Image

Question

Hi,
Here's a annoying bug. I finally found a way to reproduce it, I hope it's reproducible on other pc's. If anybody has a solution (besides not changing the background), I'd very much like to here it.
In LabVIEW 8.2:
Create a new VI, with a property node, and link it to the pane (Link To>Pane).
Select "Background Image".
From "Graphics & Sound>Picture Functions", select "Draw Flattened Pixmap"
Create a Picture control indicator.
Right Click the scroll bar, and select Properties.
Select the "Clouds" background.
Save Close and reopen the vi.
Run the vi. A nice picture of the background appears.
Change the background to "Wood - Oak".
Run the vi. Now the colors are inverted, like a color negative!
Change back to "Clouds", the colors are still inverted!
For some reason, I created an even worse situation, but I don't know how. When I start a vi, I get an inverted background image at first run, without changing my background! I Need this background to draw a semi transparent png file manually (with alpha blending), so this bug is a real show stopper. Copying the code to a new vi results in the same problem...
Regards,
Wiebe.

Well, at least I found a way to "fix" the last problem. I changed 1 pixel in the right bottom of the bmp, saved it, change the background to it, closed the vi, and then the problem didn't occure... Changing back to the old picture did cause the problem again.
