Delete Photoxx. Over the years, I've read on here so many stories/software problems. What I have learnt, the more mash downloaded the more problems.
Keep it simple, download what you need and forget 'things this new software may advance my needs' Keep it simple, as to your needs. More crap programmes downloaded, the more crap on your HD the more problems of smooth running of the system.
Ps. Don't mention Wxp he might be reading posts.
