Re: Both LR and Bridge are "skewing" or rotating certain images by about 15 degrees when view in the library.

What happens when you selected an image that has been rotated/Skewed and then  click Reset in Lightroom Develop module?

Does it change the image skew?

Next steps:-

Try to Reset Lightroom Preferences

Then Create a new catalog in Lightroom

And import these Pictures again to check if they are still Rotated.
