Select a source page keeps popping up
when I'm trying to use lightroom in either the library or develop, I keep getting the select a source page appear over the top of what I'm doing, I press cancel each time, but it re-appears constantly. Does anyone know what I am I doing wrong, or should be doing to stop this. The camera isn't connected and I've removed the card reader but that didn't stop it appearing. Each time it appears the "add" selection is lit. It's the latest version, Thanks
