Lightroom color shift between Develop and Library

I have been having a problem with making adjustments to an unusual image in Lightroom. The image is a close-up of a red(ish) piece of stained glass. I have taken it into the Develop module of LR3 and adjusted the color balance to make it more purely red. When I return to the Library module, the color of the image looks like it did in Develop for about a half second, and then it turns orange(ish). I have tried adjusting the color in PS-CS5, and the same thing happens when I import the image back into LR.

I have never noticed this with an image before. Any ideas what is going on here?

Thanks.

LR makes two preview files for every image, one for the Library and one for the Develop module. They should look pretty similar (although they are in different color spaces), but if they don't one possible explanation is that there is a problem with your color management - a monitor profile that LR is having problems reading or your OS default being set to sRGB.

However, there are other possibilities; like LR simply not revising the Library profile to sync it to the Develop settings. There are ways to force LR to rerender the preview, such as enlarging it to 1:1 and then reducing it back to 'Fit' or 'Fill'. There is also a menu command to render previews, but since I am not at home now I won't be able to help further until later.
