Netbeans will not start? Perhaps it does!

Unable to start Netbeans in Ubuntu, reinstalling it doesn’t help, installing a different version doesn’t help, tried to install from Software Centre, install from terminal apt-get command, install using the offline .sh installer, install different bundle… no luck.

From System Monitor Processes tab, it appears that the Netbeans is running, and the task appear at launcher, but I just can’t find the program on any workspace. Until I found the little 3px line on one of my workspace, on one of the display.

The program window was just too small to be found. No minimum window size? Who know?
Move the cursor onto it, click & drag to resize it, and now I’ve got my Netbeans back.

The program window move the cursor onto it click & drag to resize it Netbeans window

It may happens to any other software that doesn’t have a minimum windows size, or on other operating system. If you have a same problem, don’t reformat your pc 🙂
