folders icons keep changing size
I am using Maverick on a 27" I-Mac
Operating system 10.9.4
I set my folder icon for a particular size.
Example the documents folder is set at 84 x 84.
After working on the computer for a little while the folder reverts back to 32 x 32.
This happens in a lot of folders, and others are fine.
Even the main desktop window when you open the "Macintosh HD" window it does this too.
I have it set at 224 x 224, and it reverts back to 32 x 32.
It is extremely annoying because I have a 27" I-Mac and I can't see the folders properly.
Please help anyone.
I call Apple technical support, and they could not offer an answer.
It went to the engineering department, and had no answer either.
Thank you.
iMac, OS X Mavericks (10.9.3)
