Bitvise SSH Server crashes in win32k.sys with page fault

On ReactOS v0.4.4 (build 20170215-r73802.GNU_4.7.2) I downloaded and ran the installer BvSshServer-Inst.exe from site https://www.bitvise.com/ssh-server-download. It ran to completion (the personal license is free) but then it ran "Bitvise SSH Server Control Panel", which immediately crashed to the blue screen of death. After restart, any time I run that control (from control panel -> administrative tools), it crashes the same way. It says:

A problem has been detected and ReactOS has been shut down to prevent damage to your computer.
