Amarok version 2.8 on Linux Mint 18 Sarah Xfce 64 bit. I previously had Lubuntu on this box and Amarok's Settings menu responded normally. Now, it takes 3 - 5 minutes for the Settings > Configure Amarok to show the Configure dialog. It also takes some time for the Apply button to appear after the Local Collection > Full rescan button is pressed, and some time for the OK button to show it's been pressed and for the dialog to dismiss itself.

I tried installing Amarok while running Linux Lite v3.4 off of a live DVD and the menus and buttons responded normally.

I very much doubt this is an Amarok issue, sounds like something went wrong with your installation. You should report this to your distribution.

That's kind of what I was thinking. Thanks for replying.

Ah, what the heck. I'm bored and haven't had to troubleshoot Samba issues for a while - maybe I'll try Linux Light on it.
