The file menu on the system colours dialogue box can be used to save your favourite settings to the hard drive. After this you can point your config.pro to this file so that when you start proe it will automatically set up your preferred colour setting.
If you have trouble setting this up just reply to this post and I'll set up a detailed description of what to do with you config.pro file
Thanks everyone. I go to View>display settings>system colours> And didge on background. Change it to BLACK. And It does'nt save. So I complete the above mentioned and. Exit Pro/E. And it did not take. Tried the config option also. And it did not take. So my guess is that the administrater may control this.
