And of course if you look at Qt's source code for qplaintextedit.cpp you can see the following in its private constructor:

    viewport->setBackgroundRole(QPalette::Base);
    q->setAcceptDrops(true);
    q->setFocusPolicy(Qt::StrongFocus);
    q->setAttribute(Qt::WA_KeyCompression);
    q->setAttribute(Qt::WA_InputMethodEnabled);
    q->setInputMethodHints(Qt::ImhMultiLine);

So much for the docs being correct!

I have pushed a fix to master for this. Drops from Drag and Drop will no longer be accepted in CodeView when editing.

This should prevent your random crashes on Windows.
