Your interface doesn't work half the time

You click on a thumbnail and nothing happens. Or you click on a picture menu, like Variations, and nothing happens. Or you click on Delete All to clear up the board, and nothing happens. (Introduce checkboxes to delete several posts at once, by the way.) This is the most exasperating problem with the website. The memory consumption may be to blame. Sometimes reloading the page solves the problem, but sometimes not. One very problematic button is Delete. When that one doesn’t work, I know can usually, but not always, use Delete All to remove the post itself, which is the same thing, when there is only one picture. Delete All seems to be less memory-hungry than Delete. But this isn’t reliable either.
