Incorrect cursor placement/drawing when highlighting with mouse

[rgoring]

Expected Behavior

When highlighting text in a console using the mouse, the cursor should remain at the last cursor location and draw at the last cursor location if keys are pressed (either input from the alpha-numeric keys, or history if using the up/down arrow keys).

Windows console (cmd.exe) handles this by first un-selecting text that was highlighted with the mouse, then printing output at the last known cursor location.

Actual Behavior

When using the mouse to highlight text in a console (using cmd.exe in this case) the cursor placement moves to the top of the window and drawing happens at the top of the console window, or not at all.

Steps to reproduce

1. Run a console using the standard windows cmd.exe in ConsoleZ
2. Run the "dir" command to get a page-full of text output
3. highlight some text using click and drag anywhere in the console window (the middle works well)
4. With the highlighted text still selected, begin typing or use the arrow keys to browse history. The new input will be at the top of the screen instead of at the last cursor location.

Crash Report

[cbucher]

void ConsoleHandler::StopScrolling()
{
    // emulate 'Mark' sysmenu item click in Windows console window (will stop scrolling until the user presses ESC)
    // or a selection is cleared (copied or not)
    SendMessage(WM_SYSCOMMAND, SC_CONSOLE_MARK, 0);
}

We need to stop scrolling during selection. And to stop scrolling we call the mark command.

So this behavior is the Windows console behavior.
On Windows 10 the mark command does no longer position the cursor in top left corner.

[rgoring]

Using the windows console directly, I see the behavior of the cursor temporarily moving to the top when marking using the mouse. However, in windows console, as soon as I begin typing, the highlighted selection disappears and the text goes back to the original location at the prompt.

When using ConsoleZ, and typing while a section of text is marked, the cursor does not return to the last position as it does in windows console, and the highlighted section remains - this causes the output to appear at the top, rather than at the prompt as it does in windows console.

[rgoring]

It's almost as if ConsoleZ initializes the Mark command on the underlying console, but then does not properly de-initialize Mark when the console does to continue input from the user.

[cbucher]

but then does not properly de-initialize Mark when the console does to continue input from the user.

If that were the case , then the console will remain locked after end of selection.
Escape key is simulated to unlock scrolling when selection is done.

Mark state does no longer exist under Windows 10.
In other versions, during Mark state, Windows console should not process inputs.

What is your OS version?

[rgoring]

I'm using Windows 7 x64 enterprise. I have not yet tried it on Windows 10.
