My screen is 1360 X 768 so I can see the bottom tool bar. Also a zoom button itself would be useful since I use a track ball. Other than that I like the simplicity of the editor.
zoom button? try F is that what you mean? you can change the resolution to be 740 or something like that, i have heard that it should work fine. You can do this in options.
Jens, I'm having the same problem, only my problem is with the model editor. But unlike in the level editor, the model editor has no edit->options section to change the resolution.
There should be a settings (.cfg) file in My Documents/HPL2 where you can change settings like this.
Thank you Thomas! This is the only place I neglected to look.
