GODspedd, welcome here:-) First of all, when you open Vue, click at HELP--->ABOUT VUE and make sure you have version 4.06-02. If not, go to www.e-onsoftware.com and download the latest patch for Vue 4 (06 FULL UPDATE). If you have already Vue 4.06-02, create a new file in Vue. Then go in the menu FILE--->OPTIONS There uncheck at right USE OPENGL As thorntoa already mentionned, you may have a graphic card not compatible with Vue or OPENGL. If this doesn't help, write an e-mail to Steve Bell at sbell.support@e-onsoftware.com Please explain clearly and shortly your problem. I must say, that I did not understand what you mean with """But when i choose ANY temp...""" What is ANY temp? Please feel free to come back if you need further help. Guitta
