DHTML Backspace

Fiddling with panels in Gmod and was adding basic HTML. I can get the mouse to show, I can click on input areas and even write in those areas but for some reason I cannot use backspace to remove any text I’ve input or delete, arrow keys etc.

Looked through the Wiki and can’t find too much on this. Is there something obvious I’m doing wrong? Thanks.

Think this may be a Linux-related issue as seems to be working fine in Windows.

It IS a linux/osx related problem.

Are your backspace and arrow keys bound to something?

They weren’t/aren’t. Bound them now to just anything and still nothing.
