Well i was able to find a quick fix.
On a whim, i downloaded Firefox to see how it would handle PNGs. To my
surprise, it's able to view and save them perfectly! Even Windows Photo
Gallery and other programs can see them when i save with Firefox.
So there ya go. For every situation there may be different quick
solution's. Mine is Firefox.
As for what caused this in the first place, i believe it has something
to do with Quicktime. Alot of people have said that their problems began
after they downloaded QT. It may not be the case for everyone, but i
think it was for me.
Oh well, until Microsoft releases a proper update i'll do just fine
with Firefox. Thanks to everyone who replied.
