BlueFish Editor doesn't start

[FMark]

I downloaded the BlueFish editor and put it to the onboot.lst.
After reboot it appears as wbar bluefish icon.
When I push the icon, nothing happens.
I tried it manually in the terminal window and get the following message:

root@box:/home/tc/.wmx/Applications# ./BluefishEditor
bluefish: error while loading shared libraries: libgtk-3.so.0: cannot open shared object file: No such file or directory

It seems I have to do something more to get it running. What must I do?
(the most of my other apps are loaded only on demand, maybe a problem here?)

Install gtk3.tcz

thanks, with gtk3.tcz it works.
the upper and lower borders of the bluefish window are outside of my screen.
I can access all the menues but I can't resize or move the bluefish editor on the screen.
what can I do to get the bluefish window completely inside the screen?

Hi FMark

what can I do to get the bluefish window completely inside the screen?

Try hitting  Ctrl-M  once or twice.

I solved my problem concerning window borders outside the screen:

I found at second view in the bluefish editor at edit/preferences/user interface/dimensions the option to set the initial window height and width.
Initial window height was set to 700, in my case 680 fits.

If you can't reach some borders of a window with your mouse, in most window managers, you can press Alt+LeftMouseClick to move the hole window around; revealing parts of a window which are hidden due to low screen resolution.
