For those that work Sandboxie here in the forums,
L.S.
I work Sandboxie while scanning for opbvious security purposes and after updating MS got these alert messages - see topic txt!
You can set Sandboxie to ignore this message and wait for an update. Uninstalling the Microsoft update that causes the message is a worse option.
Always update Sandboxie to their latest beta-version to fix such irritating problems.
