I have been testing NetBeans 20 RC2 and it looks like the "Project Properties" dialog is not opening, as expected. Typically when right-clicking on a project and selecting "Properties" from the contextual menu, the "Properties" dialog should open. Unfortunately it is not working with RC2.
I also tested with NetBeans 20 RC1 and "Project Properties" did open without issues. I have tested on two Macs, one Intel and the other Apple M2 Max, and both have the same issue. Here are the details from the M2 Max: *Product Version:* Apache NetBeans IDE 20-rc2 *Java:* 17.0.8; OpenJDK 64-Bit Server VM 17.0.8+7-LTS *Runtime:* OpenJDK Runtime Environment 17.0.8+7-LTS *System:* Mac OS X version 13.6 running on aarch64; UTF-8; en_US (nb) Thanks for your time and work on NetBeans.
