lol screwloose.... could indeed be the case.. hehehe ..

That's so weird! It looks like it isn't anti-aliased.

Hey, have you tried resetting your tools to the default? If it was fine, before, and now it's not, it sounds like some setting changed.

do you see the image that way when it's full size? (100%)

thbeghin has a good point... usually I set the zoom to fit to screen and the borders screw up cause they´re like at 103,7% zoom...

lol thbeghin.....
yup.. 100%. i wanted already to complain that even the elliptical tool did not work, but then i had it indeed not on 100%.

and cynn, thanks for the tip but i also did a full reset and also deleted the prefs file.

i tested this stuff also on another pc, but it is the same.
i just made a big blunder and was thinking that the lasso tool could also make clean edges. i was wrong (god i hate to say such things!!!)

again learned something. LASSO TOOL CAUSES JAGGED EDGES!

hehe..... topic closed?

and thanks all for the help!
