Thanks for the prompt release of a version incorporating KEX Strict (PuTTY .80).
Two Windows 10 systems at a site I administer have seen 'Protected folder access blocked' notifications after installing TSVN 1.14.6. I installed it on the system assigned to me yesterday afternoon, and saw the first notification a few minutes ago:
App or process blocked: TSVNCache.exe
Protected folder %userprofile%\Documents\somepath\someotherpath\.svn\
On my system, so far, this only affects TSVNCache.exe. On another system, almost every program that tried to write anywhere in %userprofile%\Documents\... was blocked. That symptom went away when we uninstalled TSVN 1.14.6. It came back only for TSVNCache.exe when we re-installed TSVN 1.14.6. We did check the signature on the installer, and it looked good.
It looks like work-arounds should be available in the more restricted symptom case by specifying TSVNCache as an 'allowed app'.
If anyone else sees this, perhaps we can compare notes.
Regards,
Ken
