Due to continual spamming, forum registrations are now by Invitation Only. Hopefully this will be only a temporary measure to combat spammers.
If you want an invitation contact forumapplication @ camstudio . org
Sorry for the inconvenience.
I have no idea what happened, but my CamStudio has stopped working properly when I choose fixed region. The top left corner coordinates do not change when I select a different region. Only the lower left corner coordinates get updated.
