Issues with the latest version

I downloaded the latest version of WT and could not upload content to my media folder with the new version. I got the typical "this may take a few minutes" message when I initiated the upload and that message disappeared and nothing uploaded, folder not created.... I rolled back to the previous version and the files uploaded fine.

I haven't had that issue, but we have noticed today that during slide shows, the last slide sometimes won't show it displays a black screen. Closing the software and reopening got it to work for a little while.
