When I setup layers where some are locked when I save in PSD format and then reopen the file the locked layers are no longer locked.
In a work in progress saved PSD this is annoying and I have to relock the layers I wanted locked, the layer states should just be saved with the PSD but Paintstorm does not. This causes additional time to be spent relocking layers, I expect that when I save a file everything should be exactly as it was when saved.
