@Raveen : That's weird. As posted above (almost 2 years ago) I reported reverting to the DAW class because of an issue. Seemingly I unreverted at some point as I came on here to report an issue with the class and 20.0.

Got as far as tracking it down to the page procedure but it gets tangled up with Tooltips, which I don't in fact use with the fields defined as dbcombos.

Again, I'll revert to the DAW class, but do you still use this yourself?
