Dynamite Dan key definition isn't working properly

[adorigatti]

In Dynamite Dan the keys definition (selecting 'D' from the main menu) doesn't work properly... apparently it's like having an auto-repeat... so when you should define each key, the screen skips very fast through all the keys assignment returning to the main menu. If you're fast enough (i.e. very fast click on each key) then it works, but definitely there is something wrong.
