I would have placed this under ' Observation ' if there had been such a TYPE, but since there wasn't I was forced to choose ' Bug '.
I am noticing quite a bit of unstable activity on my updated clients while my non-updated clients appear to be functioning normally. Latest devprev clients exhibit slow access and slow minimize actions and often hesitate during periods of viewing. So far, cannot discern what I would call a bad memory leak.
Will upload a log.txt from one of the updated folders.
For the last several weeks I have enjoyed great faith in my clients due to my diligence in removing extraneous OEM software from my system and in my estimation the prior devprev before the latest update was one of the very best every created by the Foldit team during my tenure on the site. There are still things I might accomplish ( such as a system reboot ) before jumping to any conclusions, but I do know that normally there are not such extreme differences between my latest devprevs and the devprevs that existed previously.
