Resize the spawn menu?

Is there a way to resize the spawn menu? I like running GMod in 800 x 600 resolution; it helps make the video recording smoother. However, if I switch to it the spawn menu is way too narrow. Most of the NPC weapons dropdown menu is cut off, for instance.

So… a command line, console or autoexec thing, anything.

Nope, try the Lua requests forum, might be something there which somebody knows.
