[BetterRed]

@MerlinMama - FWIW: in the interests of tidiness, I close all codeview windows (repeat Ctrl+W until they're all gone) before and after using tools such as Spellchecker and Reports.

I can't induce your problem, as you rightly point out its not drag drop.

The icon (dialog_warning.png) is a man falling backwards. So, I am wondering if you unchecked Show this warning again on a message at some time, but I can't see where to reset them back to checked, in Editor Preferences.

I've decided to never uncheck the Show . . . again options in calibre. I did initially - out of habit. But unlike some software, calibre doesn't issue warnings without good cause. In some cases, e.g. delete book are you sure, I question whether the option to never show the warning again should even exist.
