it used to be that if i clicked on an entity and then went to the properties window I could change things ie. text, custom scale... now everything is  unavailable?  what happened?

I want to change a dimension from a 1/2" scale to a 1/8" scale... can't do it.

I want my view port to be a 1/4" scale... I have tried 1/48xp and it doesnt work and ofcourse I can no longer just change the custom scale in the properties window.

I want to change "Garden" to "grass" and now I have to double click on the text and then the text box comes up... before I could change it in the properties window.

What happened???? an answer asap would be super wonderful :)))
