you are right.. if i click on the zoombar.. then everything seems to be faster(=normal) with my modified version.
I actually see the slow behaviour too if i move the slider with an older jump version and a jump-i18n version (which is a bit odd, since the other version i did test for comparing was a newer openjump-cvs version from august last year.. so somebody did something change in between) Btw.. there is no need to fix that now.. weekends should be weekends ;) stefan Larry Becker schrieb: > Hi Stefan, > > I seem to be duplicating the Zoom bar behavior you reported without > the speed mod.
