Dream submitter is great tool, but very very buggy.
I restart this software at least 6 times a day. It crashes during auto submit, sometimes freezes and you have to kill it in win processes... Again and again. I have been using it more than year, but bugs are not still fixed.
Its run by great guys and I believe they are working on it, but there was a time I really wanted to move to another submitter just due to fucking freezing.
So I am still waiting for fixed build.
