Editing text fields

BDSup2Sub supports input checking while typing in all text input fields (including editable combo boxes):

• If the background of a text field is white, the current value is ok and/or has already been applied.
• If the background becomes yellow, the currently entered value is valid, but a modified value will be used. E.g. a valid time value will be changed due to frame rate synchronization. To see the value that will be actually used, simply press return.
• If the background becomes red, the current value is invalid and will be replaced by a fitting value (if possible) or the the previous value of the input field. To see the value that will be actually used, simply press return.
