'From Squeak3.8alpha of ''17 July 2004'' [latest update: #5989] on 16 September 2004 at 7:30:55 pm'! "Change Set: BitBlt Date: 16 September 2004 Author: Karl Hi, I got Squeak to freeze when I run Balloon3D in a combination of the autoAccessor Preference and direct hardware accelearation using Squeak3.7Gamma#5983 updated with to a FullImage to get Balloon3D. The problem is B3DHardwareEngine>>restoreMorphicForeground:above: which sends #halftoneForm: to a BitBlt instance. But there is no accessor method with this name. To reproduce: 1. disable the squeak preference for autoAccessors 2. Evaluate 'B3DSceneExplorerMorph new openInWorld' 3. select 'Enable hardware accelaration' in the morph 4. Try to open a halo on the morph It can easily be fixed if the accessor #halftoneForm: is added to BitBlt (additionally adding #halftoneForm for consistency). I would vote for adding this fix to the basic Squeak image even if it currently only affects Balloon3D and my be packaged with it.
