Hi Jewells, no worries.

Ronni does not recommend using software such as Clean up my Mac2 as it can 
cause odd problems. I don’t know if it would cause this problem in particular. 

Wondering if the cheapest and simplest way is to take it to someone (Daniel?)to 
sort out. I would hate to have to keep working on my Mac if it was doing this.

Cheers, Susan
