InDesign is the industry standard publishing applcation, i.e. it is not useless!
We need more information:
Which version of InDesign and OS?
How much RAM and spare hard disk capacity do you have?
Do you have any third-party apps, such as a font manager installed?
Are there any error messages?
Have you tried resetting InDesign back to the factory defaults?
(And welcome to this friendly forum!)
