Hi,
Question.
What is wrong with the wallet?

I have no selections in coincontroll but there is a hidden selection.
The amount of the selection in coincontroll is now not correct.
How can I resolve this?
Have you looked under the Tree Mode, to see if anything is selected in there?
I once found that problem too late, and moved a load of blocks by accident, having unwittingly ticked them in Tree Mode.
Should fix it by simply restarting the wallet. I'll look into this bug. I think that coin control dialog isn't using coinControl->UnSelectAll() and for some reason the default is to search through the dialog's list and unselect every checked checkbox. I can fix this
