CS2 (Windows XP) just started acting up on me and I have no idea why.
I was just doing post prod on an architectural shoot I did this week, combing exposures by hand via layer masks. I've been doing this for years without a problem, but what happens now is that it works normally for a while, then instead of painting in or painting out the mask with the brush tool, I'll switch to a layer and paint white or black across the image.
I figured out a workaround though - go into Layers and disable then enable the layer mask, but eventually it comes back.
Any ideas? Couldn't find anything on Adobe's site. Er correction, I didn't have the patience to wade through hundreds of documents and forum posts that didn't relate to this particular problem.
Time to re-install Photoshop?
