I have a lot of campaigns and when viewing all the adgroups i.e. 50+ with around 30 keywords in each group.. the forms start glitching and I get memory errors.
It doesn't do this with the old interface.
BTW: I remember mailing google to allow us to change the currency and they said they were working on it.. but I dont see this feature implemented.
