Project: NetBeans
Issue Type: Bug
Components: platform - Options&Settings
Affects Versions: 11.0
Environment: Windows 10, 10.0, amd64. Java HotSpot(TM) 64-Bit Server
VM, 12.0.1+12, Java(TM) SE Runtime Environment, 12.0.1+12. Apache NetBeans IDE

Attachments: IDE log.txt, UI log.txt
*What I was doing:*
# Opened Tools > Options
# In the Filter text field on the top right, typed 'web browser' and hit enter
# Saw that the filter result was already displayed because the General tab was
already open
# Clicked on the Web Browser dropdown menu, which was set to <Default System
Browser>
# The Options window closed on its own
Since then, I have not been able to reproduce the problem. Hope the attached
logs contain enough information to be helpful.
*Stack trace from IDE log:*
