We are getting a situation where a form containing a date field appears to lock up when your try to leave the field with an invalid date. We searched our code for SET NOTIFY and found no instances. Having seen the "Invalid Date - press SPACE" message a long time ago, I verified that pressing space does indeed unlock the field and allow you to fix the date, but this is a **hideous** user interface even with the message on the screen, and it isn't showing on the screen at all. Does anybody know of other SET commands or form properties that can cause this annoying situation? The other features of date fields are very much desired if we can just figure out how to give the user an acceptable notification of an invalid date.
