If I export multiple files in Lightroom 2015.2.1, the application creates 4 zero sized files and nothing happens. There is no CPU use and the user interface freezes if I click somewhere else or try to cancel the export. I tried the following:
- Disable GPU support.
- Disable "Show Add Photos Screen"
I successfully tried this:
- Create a new empty catalog.
- Import all photos for the export from the original catalog.
- Export with the same options.
But of course this is no final solution. My catalog is huge and well organised. I would like to keep my original catalog and export images from it.
This is a known issue with Lightroom 2015.2.1.
would suggest you to revert back to Lightroom 2015.1 for the export process.
