 The caret in the SharpDevelop Editor remains visible when the <Esc> key is pressed to close the code completion drop down and a cursor key is used to navigate away from the current cursor position.

 Steps to reproduce:

1. Open a C# source file.
2. Type a character that opens the code completion drop down
3. Press <Esc>
4. Navigate the cursor using any of the cursor keys e.g. <down>
5. You will see two "cursors" one vertical line and the "standard" blinking cursor.

SharpDevelop version 3.0.0 build 2786

I cannt recreate your problem in #Develop2.2,1.2648.

 Hallo Yang,

I just reproduced the issue in 2.2.1 build 2648 and I can confirm that the same problem is there as well. Please let me know what I can do to help reproducing the problem.

Regards, Boris.

 I'd just like to add I also frequently had this issue, but found it hard to properly reproduce. I think it depends on wether the caret is obscured by the completion window.

 

I just solved the problem by modifying the code:

In TextArea.cs there is a method 'ExecuteDialogKey(Keys keyData)'.

In that method, find a part of code that says:

finally {
                    motherTextEditorControl.EndUpdate();
                    Caret.UpdateCaretPosition();
                }
                return true;

and change it to :

finally {
                    motherTextEditorControl.EndUpdate();
                    Caret.RecreateCaret();
                    Caret.UpdateCaretPosition();
                }
                return true;

After that recompile the code and the problem will get solved.

It worked for me, let me know if it works for you too.

 How am I supposed to check-in the fix for this bug?

The solution which I posted earlier doesn't work on SharpDevelop version 3. In solve the problem in version 3, I commented following lines from 'HandleKeyPress(char ch)' method in 'SharpDevelopTextAreaControl.cs' :

                    if (codeCompletionWindow.ProcessKeyEvent(ch)) {
                        return true;
                    }
