Spark 2.8.3 freezes when chat window is closed

Spark 2.8.3 on windows 8.1 pro

I am having an issue with one of my users. Many times throughout the day when they close a chat windows Spark freezes up on them and they need to close the program from the task manager.

I have tried renaming their transcript folder and forcing Spark to create a new one. I have also tried a fresh install.

User is still having same issue. Looking for anything else that might be a known issue or resolution for this problem.

Thank you

Hi

Is this happening frequently or there are times?

Try upgrading the Java and uninstall the spark client, delete everything in the installed folder.

Reboot system after upgrading Java

Install spark again

Does he/she has whiteboard or any other unofficial plugin (File > Plugins)? Also check the logs C:\Users\User\AppData\Roaming\Spark\logs

And if you want to start fresh, then rename whole Spark folder, not just the transcripts. You can then copy the transcripts from the renamed folder to the new one. Maybe also spark.properties file with settings.
