Vasu squinted. She zoomed in. He saw the familiar Kannada script, the local report about the Kambala (buffalo race) being postponed, and the weather warning for Udupi. But then, he saw the front-page headline:

Vasu grumbled. “That tiny screen? That’s not news. That’s a headache.”

That evening, Vasu did something he never thought he would. He took Nidhi’s spare tablet, bookmarked the website, and whispered, “Teach me how to zoom.” Karavali Munjavu Kannada News Epaper Karavali Munjavu

“No paper, Appa,” his granddaughter, Nidhi, said, tapping her phone. “But I can read you the news.”

Dark background on some thumbnails

a folder with two thumbnails whose background is entirely black

Clear your Explorer thumbnail cache (see above) or copy the file to a different location.

This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.

I can’t do anything in my program to work around it, I’m afraid. Please use the Windows 10 feedback function to report this to Microsoft. If enough users do it, they may eventually fix it. Windows 7 does not have this bug.
