Most times they usually still respond to the keyboard and mouse, and sometimes I can still copy+paste passwords and things, but it is incredibly sluggish. I use codebook on Windows 10 Versionē Build 18363 on a Lenovo ThinkPad T470s running an Intel i5-7300U CPU 2.60GHz with 12GB of RAM.įor some time I have the problem that Codebook and the Secret Agent lag and slow down or freeze.
