I'm sure you're right. Only thing is that the glass surface is not
becoming damaged or scarred or dull in any way. You wipe off the sweat
and the glass looks as good as new. It's just weird. Anyway, I think
I won't tell her that her paperweight is "diseased" since I bought it
for her... hehehe
Thanks a bunch for your diagnosis!
