Re: Why is Scintilla doing this?

If I call this before showing the file dialog:

const auto line = m_edit.GetFirstVisibleLine();
const auto pos = m_edit.GetCurrentPos();

And then at the end, wther they click OK or cancel to that dialog, I call:

m_edit.SetFirstVisibleLine(line);
m_edit.SetCurrentPos(pos);
m_edit.ClearSelections();

It works. Position stays the file, nothing selected. But the caret is right 
at the start of the document.

If I swap the lines:

m_edit.SetFirstVisibleLine(line);
m_edit.ClearSelections();
m_edit.SetCurrentPos(pos);

The caret ends up at the right place, but now everything is selected from 
the start of the document to the caret.

I can't win.

Is there no way to get the editor to temporarily stop doing anything ?

Tried SetRedraw with false and true and it didn't quite work.
