I don't know if it is just me or what, but more often than not, when I click on a photo (to enlarge it) .... the photo opens up but has some "filter" (?) covering it. I usually have to x out of the photo and click it again to see the actual clear photo without some blue-ish overlay.
When I click on the thumbs up or give an acorn to a member in their post, the icons are not reflecting it. So, I've been known to hit the icon again accidentally giving another acorn because no number shows next to the acorn icon to reflect that I had already given one.
Using the thumbs up, I have to click on the icon several times before the acorn icon turns gray to let me know it accepted my thumbs-up and added it to the total thumps up for any post or photo.
