Disable proxy use in Momindum Maker
Momindum Maker 10 blocks for a few minutes when opening the next screen before going to the "What do you want to do?" screen, this may be a problem with the connection to your network proxy.
To solve this problem, you need to open the Momindum Maker editor (MK icon in white on your desktop) then go to the "Preferences" menu then "Network" and finally choose "No proxy" then click on the Save button.
Now, if you try to re-open Maker 10 by double-clicking on the MK icon with the black background, it should open much faster.
