When I upload images from my computer, select several images in a folder, before pressing Upload the filename-and-size list shows the right info. When I click Upload, many of the images are repeated into the wrong files. If I select one file at a time and click Upload once for each file, the images are each uploaded fine.
A second issue: I can use the WP Media uploader just fine to upload many files into my media library -- but then to copy the images into 1 Flash Gallery I have to check the box next to each image because there is no check-all-boxes box. Not a failure, just an awkwardness in the user interface.
Third problem: Can't upload a Zip file. Clicking Upload produces a popup with an Alert exclamation but no message.
