Is there an error message?
What is your operating system?
Did Lightroom 5 ever work properly?
Still the same problem. Doesn't matter how many
catalogs I create. LR opens and hang-up. When I attempt to click on a
task I get a a dialogue box with two options one is to wait for the
program to open and the other is to close. If I wait nothing happens so
the only option is to close. The only way to open is to delete the file
preferences.agprefs and then reopen LR 5. So I keep teh program running in background but when I need to exit LR 5 or reboot the same issue repeats itself.
