I selected everything using coin control, still cant even move <1000 coins.
Will try again tonight
Yeah, it is a pain in the ass, I admit. When using coin control you can see the current size of the transaction as you add inputs. The max size right now is 100,000 bytes. It is a good idea to occasionally combine your inputs to keep your wallet slimmed down and to allow for larger transactions when you need them. I was thinking in a future release I would bump that a bit to more accurately reflect the size of of some transactions. That would work, but is kind of a bandaid. With 1MB block size 100KB only allows for 10 max size transactions per block. A better fix would probably be some kind of auto-combine function. I am open to suggestions on how you guys would like to see this dealt with.
There is a quite easy solution to this:
1) Generate a couple of new addresses to consolidate to
2) Change to the "Send" Tab
3) Select all inputs in coin control with one click
4) Add additional Receipients (the previously generated ones) with the "Add Recipients" Button on the bottom left
5) Send, ignore the transaction size marker
If you added enough Recipents, it will work in one run. Be careful that you don't list the same address twice, or you will get an error message.
You will get a single transaction sending everything you request. Of course, a large transaction with lots of outputs will incur a higher fee. It should still be less than sending all transactions separately, however.
