What could cause IDEA to stop displaying dialogs?

Reinstall from http://www.jetbrains.com/idea/download/index.html, delete IDE directories to start over (https://intellij-support.jetbrains.com/hc/articles/206544519). Provide the logs (https://intellij-support.jetbrains.com/hc/articles/207241085) if the issue persists.

Well, I tried what you suggested (more or less), and the problem only went away when I uninstalled JDK 1.8.0_152-b16, reverting to 1.8.0_131-b11.

You are using some weird build, please make sure to install and run 2017.2.5 from http://www.jetbrains.com/idea/download/index.html.

Thanks. As I said, I am not ready to switch to a newer release.

The logs do not show any errors, so I can't tell what's the problem and how to fix it, sorry.

Running under a more recent JDK build may help: https://intellij-support.jetbrains.com/hc/articles/206544879.

The problem was that my custom build did not include the JetBrains custom JDK, so it was running on an Oracle JDK. I was able to reconfigure it to use the JB JDK and the problem went away.

When building IDEA on macOS, is there a way to configure it with the JB JDK?

Alan,

currently there is no simple way to build Mac OS version of IntelliJ Community with bundled JRE. JRE is bundled with dmg archive which is built only if org.jetbrains.intellij.build.ProprietaryBuildTools.macHostProperties is provided. So you need to modify build/scripts/idea_community.gant to pass a proper instance of ProprietaryBuildTools class to BuildContext instance, follow the javadocs for details.

Thanks.

The JB SDK Bintray Downloader is not working for me (it says Updating... forever), but presumably I can copy the jdk from a public release.
