a trick for ms windows users: if you need to start expert lotto with expertlotto.cmd command instead of the regular start menu shortcut (e.g. because you want the application to use more memory) you can get rid of the command prompt window by modifying the .cmd startup script:
edit the last line in the script:
java -cp <the rest of the line>
to look like this:
start javaw -cp <the rest of the line>
