Problem with Scaling tool

[Deadwalking12345]

Alright here's the issue, i imported new textures for a skydome and wanted to re-size the skydome. When i picked the normal scaling mode, it wouldn't let me. thinking something is wrong, i tried scaling a light (make the light range longer) but it did not work either. Then i selected the brush and used the normal scaling mode and non-uniform mode. none of those work. The only way i can scale things is by typing them in. However i much prefer clicking and dragging to re-size/scale. Thanks for taking your time and reading this. I would love a reply with info to help me restore the function i wish to have. THANKS!

Do you have the camera selected in the tools on the left hand side? (top left icon of the tools).

If you mean camera mode underneath the modes and above the brushes, then yes.

if this is the issue (hope i am not sounding extremely nooby) It will not let me stop using the mode....
