> in the canvases. I implemented some synchorinzation in between the

> the mouse over their bounds. everything is fine at this stage. I use a
>JSplitPane where the canvases are directly embedded in.

> The lower splitpane is empty from that point. What has
>happened??? I did't see this behavior with the current jdk1.3.1. For

>me for posting images again; i tried to make them as small as possible)
>
>- moreover i thought that they did improve something on the resource

>with canvases embedded overdraw their frames).
> Can someone give an update on this issue.

There are problem when underlying graphics context is
initialize using JDK1.4 with Java3D:
4470749 -Java3D fail to initialize underlying OGL/D3D library in jdk1.4
sometimes
This in turn expose a bug in Java3D :
4474411 - Crash at resetTextureNative() when OGL context fail to create
