thanks for the tips.
iīve reduced the cache size.
downloaded the dash off thing and it seems to be working.
and , yes you can assign the cache to an external harddrive. at least it give me any trouble, when i did it . but than iīm on an intel mac, which may be different from your one.
so iīll have to check a bit more, but all that seems to have given me some more speed.
although i still think the general behaviour of NX is quite cumbersome.
for instance , when youīre doing whitebalance it always switched to closed side menues and stuff like that.
letīs hope for the best, thanks again.
