I found an earlier post where the poster had the same issue...
I've tried both the Focus event handler an the OnEnter.. Both I've tried running the select all method and SelectAll followed by Invalidate or Refresh.
Do you now if that's a known issue in 7.2?
Thanks.
This is typically a timing issue.Try using a BeginInvoke to call SelectAll instead of calling it directly from the event handler.
For those interested... This seems to work.

}
delegate void SelectAllDelegate(UltraMaskedEdit textBox);
void SelectAllOnTextBox(UltraMaskedEdit textBox)
