saving problem

hey. just wondering if anyone could help me out

experiencing a huge problem with my CS3. i open an image as always, edit it as always, then save it as jpeg, as always. but now the jpeg is a lot darker when opened in anything other than photoshop or opened online.

this is has only started happening since this afternoon, no idea why i havn't messed with any settings.

ive googled the problem and it seems quite common but everyone seems to solve it by making it sRGB... but i'm already on that so im out of ideas.

here is a screenshot of the file in photoshop, next to the saved jpeg opened in paint



screen shot of my colour settings (which have never been changed)



help would really be appreciated

Hm...
Tell me, when you save as JPEG in PS, normally there should be a small dialog that ask you for the quality of the pic, always make sure that it is at 12, sometimes the little bugger changes the value on its own...
