used dspurge utility, & did a fresh instalation. Version 11 Beta 5 .
System hangs, & force closed it.
i have gone back to Windows 10 , & tried this version 11 beta 5 on windows 10. Problem persists.
i uninstalled this Beta version & installed older version 10.03 . It is running fine on windows 10.
now i am upgrading once more to windows 11 , with the old version of Deskscape , to check the status.
