Non compatibility in use the Preferences.txt for windows settings about wings

[dgud]

terminate: {plugin,sel_groups} (wx_deleted)
Comes from wpc_sel_win:293

setCurrent failure probably comes when you are deleting a geometry window, should be ok most of the time.

We are supposed to make the new version so good they never will turn back :-)

I think I already comment about this before (by email, maybe)...

Because the code is using the preferences variable saved_windows to store the float windows if we dock all the windows we were using the in old Wings3d version the preferences is getting both variables (saved_windows and saved_cont_windows) filled with the same windows:

{saved_cont_windows,[{split,splitVertically,836},
                     {split_rev,splitVertically,169},

Here is the crash dump and I attached my preferences file

Fixed by saving all window info in 'saved_windows2' pref for new wings versions in pref files.
