Sorry, I misunderstood your question.
(I thouht you want to use "lock" function)
The most part of ipmsg users don't uncheck seal checkbox.
So I removed this default check settings.
If you want to uncheck it as default, change a following registry value to 0 after terminating ipmsg.
\\HKEY_CURRENT_USER\Software\HSTools\IPMsg\SecretCheck
