Proscene v2.0.0-beta2 is out. Download it here and extract it to your sketchbook libraries folder (automatic importing Proscene from your PDE is only available for stable releases, currently v-1.2.0).

This release fixes a nasty bug introduced in the previous beta which made the scene dissapear when dragging with the mouse center button. Thanks to Amnon Owed for reporting it. We encourage all Proscene2 users to upgrade to this version.
