Hi,
I have found a problem:
TPlannerMaskDatePicker when set ShowModified:=True,
When edited, the font color is properly set to modifiedcolor
but after the focus is lost, the font color goes back to default.
Delphi Xe4,W10, TMS Component Pack v8.8.1.0
Thanks for reporting.
We traced & solved this issue and can confirm this will be addressed in the next scheduled update.
