I have updated to Windows 10, I have the most up to date version of Lightroom, my diplay adapter is an AMD Radeon HD 6450 with the most up to date driver, and Lightroom crashes everytime I try to do something in Develop. Ideas?
There was a driver issue with AMD using previous Windows OS which may be similar in W10. The solution was to go back to an earlier driver temporarily.
