I get it repeatedly with 2256 e.g. on our forums, https://forums.bistudio.com/

Thanks a lot for the report. We have added new MS Supported API support (AMSI on Windows 10, and IExtensionValidation for IE on all platforms) to increase the effectivity of script/ActiveX scanning. So this is something new. We’ll try to repro this. Thanks. Lukas.

seems to be fixed in 2257, good job
