Hello,
Please run the demo Actiontest.exe,you'll find that the Blue Bar for the selection is disappeared inexplicably when you right click the blank space, but, if the cursor is in the selection, all is correct.

How to make the hightlight bar that indicating a selected item not disappear when I right click?

Yes, right click outside the selection deselects and moves the caret to the point of clicking. The same behavior you can find in other editors, such as Notepad or MS Word.
To disable this behavior, exclude rvoRClickDeselects from TRichViewEdit.Options.

Thank you very much. it works correctly now.
