This is a bit weird. i'm not sure if it is a JRE/Swing issue or a NB issue, but the little down arrow to the right of the source file tabs that pops up a menu to select from all the open documents isn't working when it is on my primary monitor (Thinkpad Laptop), but if I drag the NB window so that control is on my external monitor, it works. If I unplug the external monitor so there is only one display, the popup works on the primary (built-in) monitor.
Has anyone experienced anything like this? Do you have a solution? NetBeans 22 Ubuntu 24.04, JDK 17 or 21 Regards, Scott
