Currently, some of the controls from the suite are using custom cursors. They are optimized for 96 DPI only. If you set a higher DPI the custom cursors remain small compared to the window cursors. Created several sets of cursors (.cur) and apply different ones for the different DPI. This can be done for RadDiagram, RadSpreadsheet, RadRichTextBox, etc. Original Title: The mouse cursor is too small when DPI is above 100% Original Description: With the Diagrams control/Spreadsheet ,the mouse cursor is too small when DPI is above 100%,looking the attach files.
