I have a Delphiproject that suddenly got its appearance changed. It used to have rounded buttonedges but now got suddenly sharp corners. Also the MonthCalendar changed its appearance with blue ribbon at top and the current day circeled with a broken red circel line as it had many years ago. I use Delphi 2009, but open the project in XE4 gives the same result. XE4 has an Application.Appearance, but I can't find the solution there. Any suggestion ?Click Here
