When the issue occurs that you cannot apply a new dream, could you take a post a screenshot using Regedit showing this set of keys : HKEY_CURRENT_USER\SOFTWARE\Stardock\Deskscapes before and after changing to another dream file (which fails obviously)
We cannot reproduce the issue here (and we have tried!) and would like to narrow it down to if it is a problem decoding dream files, applying the dream or it not reloading dream settings.
I saw a report saying they could still apply videos and static walls from DS but just not Dreams?
Also as a note to anyone using DS10 b1, that will expire on Thursday morning.
