and armory has some problem too
Can you explain please? I have played it with and couldn't find problems that even Electrum had. Electrum was too buggy and slow when it had many addresses. It has been solved, I think.
Edit: ThomasV told it is optimized/fixed and it will come with version 2.1 . Hope it works!
i didn't check it my self, since i love bitcoin- core too mucht, but here there is this guy experiencing some problems
