OBM not holding settings

Minor quibble here but its begun to bug me. OBM wont seem to hold my preference settings. For example i need to consistently reopen tool boxes, I have two application windows open and both windows open on the same monitor every single time OBM is opened. I just want to set up OBM once and not have to keep resetting it up every time I use it.

I dont know what the problem is but its never ever worked properly for me. other users here dont seem to have a problem, however, im running windows 10 and they are on windows 7.
