I've posted re streaks in TMX 100 new.
Well, I had it again (less, but they were there) - and this time everithing went smooth - very strange.
So I decided to refix on freshly mixed fixer - et voila, gone!
It seems related to old fixer (not exausted, used to fix just a few 15 exposure strips), Polymax T diluted some 2 months ago.
Note: I hasn't paid attention to it, but the film had a slightly pinkish tone, now it's completelly clear.
