Do you mean it is not working at all or that it is not very precise? Full screen seems to be an enlarged (as opposed to scaled) version of the project. It is hard to have much control when clicking the slider.
Could you add a chunky sprite to click on and adjust the value of the slider from a script?

I mean that the "tweak by one" feature added in version 1.1 of scratch isn't working in full screen mode.
Try it with the spiral pattern projects I have uploaded. Using the slider you can't get all the values from 1-100, (not enough resolution) so you have to click *next* to the knob to get it to increase or decrease in single steps. It's that fine-tuning which doesn't work in full screen.
Yes, I could add a workaround but it's clearly a bug.
