It seems like you are hitting a known issue which we have logged on our public portal: RadSpellChecker window appears behind its parent window when the parent window got the focus and SpellCheckingMode is AllAtOnce
. I am afraid that we couldn't find a workaround for this case, though. Could you please check the public item and confirm if the behavior you are observing is the same? If it is not, we would much appreciate if you can share more details on how we can reproduce the issue so we can further investigate it.
