When you copy the CC number from a saved CC, please change it so it doesn't copy the spaces between each 4 numbers, or allow the removal of the spaces from the saved number.

When pasting the number into fields, some aren't smart enough to throw out the spaces but are smart enough to not allow more than 16 characters, and the last 3 numbers don't get pasted. Then the user needs to manually removed the spaces and manually enter the last 3 numbers.
