I already have a light blue glow around it.
Also, I'm having some problems with saving in photoshop.
On my sister's profile it takes about 2 seconds for the save box to came up and save the file. But on my profile it takes 5 minutes (I'm not exaggerating either) just to pop up, then I have to wait for all of the files and folders to show up in the directory that it is exploring. Any ideas?
Yes you probably have a huge document open. i.e.: The document is at 32 Bit or you are working at a huge resolution, which would cause the computer to slow down dramatically if you don't have sufficient RAM.
If you're starting off with space scenes, you could have a look at this tutorial.
Again, it's probably because you are working with a large canvases/resolution. If your computer is of the older generation it will likely seize up whilst trying to perform at Photoshop's high processing demands.
