I tried playing glitch on my notebook and the screen was too small, but there was no scroll bar. I would like to suggest adding scroll bars to the flash application, since the built-in ones for the browser don't work.
Try using your browser's full screen mode. In Firefox, you'll need to go into the options on the toolbar to add the 'full screen' button to your toolbar (for easy access). In Chrome, I believe you can press F11
I use a netbook too sometimes, it's impossible to play without using fullscreen mode
Yes, I tried the game on my netbook a test or two ago, and with Chrome it worked fine (albeit a bit slow) in Full Screen (F11) mode. No need for scroll bars when in full screen mode. I plan to be playing much of the next test on it, because I'll be traveling and I take my netbook with me for trips.
