Hi - I *may* have cleared things up by uninstalling / removing all of the Java3D instances on my machine, then reinstalling 1.2.1_04.
While my graphics come up initially, and I don't get the OpenGL-related errors as before, I now have some kind of refresh issues with my Swing menus, split panes and dialogs. The display intermittently blanks out completely or fails to refresh a subregion where a Swing component has overlayed it. Can anyone help me out here? thanks, jp -----Original Message----- From: Lee, John P (DIS Boston) Sent: Tuesday, June 11, 2002 11:22 AM To: [EMAIL PROTECTED] Subject: [JAVA3D] JDK 1.4.0_01 and Java3D 1.2.1_04 problem... Hi: Apologies if this is a re-hash... I have looked around and thought I was on the right track. I was using JDK 1.3.0_C with Java3D 1.2.1_03, and had to upgrade my JDK to 1.4. This did not work with J3D 1.2.1_03 - I got a blank canvas and the following error messages: wglCreateContext Failed: The handle is invalid. wglMakeCurrent Failed: The handle is invalid. extensionStr == null So, I looked around and decided to upgrade Java3D to 1.2.1_04, which I thought would work, but alas, I have the same error. Can anyone help me out?
