Keyboard/mouse problem after Create/SetGraphics()

Code below should exit on ESC or LMB - neither works. Seems that nothing from PolledInput is working. Have Quickbuild off, Debug on/off makes no difference, gl/dx makes no difference, have rebuilt all mods.

I also seem to be suffering from a 50% drop in FPS since upgrading from 1.18 to 1.20 when running under DX.

gfxObject:tGraphics = CreateGraphics(800,600,0,60,GRAPHICS_BACKBUFFER)
SetGraphics gfxObject
While (Not KeyDown(KEY_ESCAPE)) And (Not MouseDown(1))
  Delay 1

this is in the source code for EnablePolledInput()

So apparently CreateGraphics nor SetGraphics enables the Polled input.

As TomToad mentions, CreateGraphics alone does not enable polled input.

What's wrong with just using 'Graphics'?

Well... nothing.

I came across this issue as part of my investigation into why my game's FPS has dropped from 30fps to 15fps simply by updating from 1.18 to 1.20.

ha this one caught me out too a while ago.

Why is it you chose to enable polled input in the Graphics command, Mark? :)

Just seems strange as they're pretty unrelated :)

Just as a little side-note here... is it possible to manually enable PolledInput after using CreateGraphics(), then? I can't find anything in the documentation pertaining to this.

guess what ... EnablePolledInput() :-D

Although I've just got rid of PolledInput from my framework to use event-based input instead.

What Grey said. I use it to enable polled input when I'm in Windowed mode so I don't have to have two sets of input fuctions and I don't have to keep track fo the state of every key myself. The only caveat there is you need to make sure you enable the canvas each frame or else the input will go elsewhere.

How the hell do you find this stuff in the documentation? I still can't find that!

It's not in the docs. I found it when I was trying to debug, and clicked the source button at the top of the section with the graphics function, and looked in the graphics function to see the command there, unhighlighted.
