startlazurus shows "Access violation window" lazarus / 1-Linux ---------------------------------------------------------------------- geek893 · 2016-06-21 07:20 OS: Debian Unstable, Xfce 4. Lazarus: 1.6 FPC: 3.0 The window: https://i.imgur.com/5LCNu4v.png I get this error when I launch startlazarus with Xfce4's Application Finder: https://i.imgur.com/xlLUEK5.png No matter what I click, either "OK" or "Cancel", the program closes. But I'm able to use the program if I run startlazarus from Xfce4's terminal. ---------------------------------------------------------------------- geek893 · 2016-06-21 12:28 Problem solved. I removed Lazarus with all configuration files and then installed again. Something was wrong with my configuration. (Although I previously deleted  ~/.lazarus , but it didn't help. Strange)
