Hi, when I opened my gimp today, and I have found some icons that have gone from my tools box on the left-hand side. I clicked to edit- preference-window management, reset my window position by default value, and click OK. Then I restarted my gimp, but the tools box still does not show the buttons I am expecting.

I went to windows- and I clicked to the recently closed dock, which is still nothing help.

I uninstall the gimp app and reinstall it again, but terribly, the same problem remains.

Please advice me on what can I do to restore the complete set of the tools box.

Guys, please see my screenshot for what I have attached.

I need the original tools-box with full buttons.

Thanks
