This morning, I had an incident of Mids running (minimized) and didn't realize it when I clicked the icon to run it. The update dialog popped up, and told me to close all existing incidents of Mids, which I did. But something went wrong, and the update box kept popping up until I had to use the Task Manager to close it.
Tried running Mids again, and the pop-up box again kept popping up. Tried it several times, and could only close it with the Task Manager. Finally looked to the website to download the new version, and saw that only the update was available for download.
Finally I uninstalled Mids and reinstalled it with my archived copy of the program. Then it updated properly. I'm not complaining but wanted to let you know of the problem I had due to an odd problem of having an instance running when I tried to start another.
