Since the most recent update (2015.9) i have trouble opening lightroom - the first time i try and launch the program nothing happens but when i go to task manager i see that lightroom is open as a background process and it's using about 90% of CPU. When i end the process and re-launch the program it works perfectly fine. Interestingly Photoshop launches without a problem and if i launch photoshop first then Lightroom always opens without any hitch. I feel like i'm missing something in the LIghtroom launch sequence.
Anyone offer any help - i'm not too desperate to correct this if it involves uninstalling and reinstalling - it's a little annoying but not a disaster.
To correct, try the following procedure-
1. End the process in task manager and re-open Lightroom , and then open the Task Manager. (CTRL+ALT+DELETE)
2. Set the Priority of Lightroom.exe to High (see 3 images below), close Task Manager.
3. Close Lightroom,
4. Restart the computer,
5. Reset the Preferences of Lightroom by holding [SHIFT+ALT] as you re-open Lightroom.
Hopefully this has solved the problem.
