<P><FONT SIZE=2>Thanks Chris:</FONT>
<BR><FONT SIZE=2>I am completely blown away with the power of Magma. I've used object databases before but not one as transparent as this. It swallowed my whole radio and spat it out again intact. Really there was only one line of active code that saved the PasteUpMorph on which I built the radio. There is only one tiny thing I can't figure. My connectors come back connected unless I close the morph. Then the next load from the database they are disconnected. Still in place but the ends floating. Do you know of any way to close the morph without this happening? Also if I put in a window it restores without the window. I think I understand this because the window is not the root object. If I could get a reference to the window somehow and commit that I'm sure it would work. </FONT></P>
