With lxpanel 0a92dd7c59ca48549fec52439243f46a1fc21f9e and using LXDE
- launching some applications like lxterminal, xterm and so on
- on lxpanel taskbar (window list), choose such application item and click mouse right button
- then choose "Maximize" (note that my environment is Japanese so the word may not be exact)
Then such application's window does not get maximized, although
- For gedit (3.22.0) doing maximization from lxpanel taskbar works.
- When clicking mouse right button on the title bar of lxterminal (for example) window and choosing "Maximize" on the title bar, it works.
Note that I compile lxpanel with GTK2 (2.24.31).
Thank you very much for reporting this issue. It should be completely fixed now in GIT sources.
Tested with d7022af2b3003083220f23ad0aaf4a11d7706074 and looks good, thank you!
