Version of LR?
Version of OS?
How do you change to the develop module after selecting a photo?
Can you post a screen-shot?
You can try reset the Lightroom Preferences back to default and try open the same catalog again.
If you are using Lightroom 6/ CC 2015, use the below instructions.
Go to the Location:
Mac : /Users/[username]/Library/Preferences/com.adobe.Lightroom6.plist
Windows: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 6 Preferences.agprefs
then rename the preference file to Lightroom 6 Preferences.agprefs.old
Launch Lightroom with the same catalog and try it.
Let us know if that helps.
hi. tried that but didn't work. still pops up on screen. very annoying.
I have lightrrom 6 on windows 10. click on develop next to library.
And you're sure the preferences got reset? Us the following way: Hold down Alt and Shift while starting LR. This brings up a dialog for resetting the prefs.
If this does not help, please post a screen shot of your screen with the message on it.
