Thanks eon but still no luck, the graphics card is an Nvidia GeForce4 MX, it has the latest driver. I have seen reference to the fact that Vue can have problems with Nvidia maybe thats where the problems lay, obviously I would not change my graphics card because one program was incompatible with it, at present Im am still on Windows 98. I just cant figure out why some of these problems appeared with updates, the problem with the options sudden failure, and then the next update it worked okay again, it just doesnt tie in with the performance of other programs. I only put the preview fault on because it was easy to show, but why should it suddenly appear after an update, if the graphics card is causing it, then logically it should have been like from the first time I used Vue. I do find the programs that behave by far the best are self contained no installation, like C4D, just delete the folder if you wished to uninstall for any reason, I hope more software companies go down that route in future. The first time I ever uninstalled Vue and then checked, half the stuff was still in, with a self contained delete the folder set-up that couldnt happen, and I dont know whether Vue shares files, but I am sure that in some cases that causes problems and clashes. Anyway thanks for trying, if you can come up with any idea why the use of Vue causes the lockup when I try to shut the computer down, unless I have everything off in start-up programs, that would be most helpful.
