Well, keyboard was not the problem. Tried a new keyboard last night and the problem still appeared. Everything went well for two hours. I was done for the night and when I closed down the control software, I got an error message that the control software had to shutdown. This was after I had already clicked on closing it. After it closed and I cleared the error message, I opened the software back up and that's when the problem showed up.
Shopbot support wants me to uninstall and install the software a second time, but do a computer shutdown between the two. If that doesn't cure it, I may just have to switch computers.
