I'm more than a little gutted that having trialled Vue 4, bought Vue 5 and recommended it to many others I seem to be having the worst experience with it of anyone I've spoken to. I already had to reinstall the original disk version (after uninstalling 2 automatic updates) after Vue wouldn't open some of my files. After a few weeks of operating satisfactorily again Vue now hangs for up to 15 minutes when opening certain files. It's actually worse if opening a new blank file! Some Vue files have become enormously bloated for no apparent reason. A 1.2Mb file which had been worked on and saved several times without problems suddenly became 243.7Mb, despite no additions of materials or geometry. Material previews often become blacked out. This has no relation to material preview settings in the Options window. I have had problems from the start of not being able to save atmospheres in some files. I got around this by saving the file under another name and deleting all geometry. Hardly satisfactory though. Options, Render and other pop-up windows stay frozen in the Vue window until I hit Ctrl+Alt+Del, impeding access to any other commands in the main window. This has just started happening in the last 2 weeks. Of course one suspect for some of these issues would be OpenGL support or lack of it, but I'm running a fully-supported nVidia GeForce FX Go5700, which passes Vue's in-built OpenGL test. Running P4 3.2Ghz, 1.27Mb RAM. As computer visualisation is my livelihood I'm pretty upset that Eon would release software as unstable as this. Can anyone offer any advice? Many thanks in advance, Jackson Barkess
