If you had a web browser open at the same time, with lots of open tabs and tons of web sites, that could chew up considerable amounts of virtual memory.

My first thought was that the batteries in my wireless keyboard might be flat, so I fitted new ones – no change.  I also saw a post recently that DX log had a few issues perhaps when the cluster traffic was very high and I wondered whether W_T had developed an issue. Of course traffic was high this weekend and although I had a separate computer on the network handling the link to VE7CC, the logging computer still had to accept the incoming spots over the network. So I killed the ethernet link and that made no difference either.
