Selecting files as attachment

Question

Selecting files as attachment by clicking attachment icon and subsequently folder, subfolder and file worked fine till today.
All of sudden mail stops at first level of folders with effect that mail attaches all pictures - yes this took some while - instead of allowing to select a single picture. Doesn't matter if you select or unselect the icon for windows compatibility.
What's wrong?
Thanks for your kind assistance
