Hi,
One remark about memory consumed in OJ. When I load a shapefile with 36 580
polygons (size 18 mb) the memory using by my java virtual is up to 202 mb.
If I minimize my OpenJUMP windows and I open it again the JVM display : 85
mb.
R1.

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 ;)
