I'm using Lightroom CC, and today a new irritating thing is coming up.
When I'm exporting an image the Choose Folder dialog comes up every time, even when using presets that I have used many times before. If I select the folder it works as it should, but it's very annoying to have have to repeat this for every export. This is why features like "Previous Export" and Presets are there to solve. Why has it started to always ask where to put the files, and how to get Lightroom's memory back again?
Can you post a screenshot of your export dialog?
solved it. It was volume ownership issues in Windows. Sorry for not checking that before!
