Workaround the issue by not using Shadow REDEFINE TITLE oTitle ID 123 of oDlg SHADOW NOSHADOW No joy. Please try to reduce the height used by TScrDlg() I reduced the controls from 10 to 7 sets. Seems painting issue is consistent. There will be extra bits painted near the 5th, 7th and 10th TTitle
When I added up to 10 RTF controls within the same page on the TFolderEx, the screen painting starts to become weird and folder names got painted where it shouldn't exist.
