Checkin Dialogbox - OK button needs to be active by default

[RoyWickrama_RWEI]

Having opened a several files (say drawings), I check them at the closure. Mostly, no comments entered. Therefore, OK button should be the active button in the Checkin dialog box so that pressing the ENTER button will simply CHECKIN the document.

Note: I tried my best to (without success) to find some iLogic code for this purpose.
