My cursor/brush disappears as soon as it goes onto the canvas (I can select brushes, colors, etc. in the menus and tool bars just fine) and is unable to interact with it. Furthermore, I'm unable to manipulate the canvas in any way, including rotating, zooming in and out, and cropping. This is the case with all canvases and templates. However, when I exit out and the "do you wish to save" window pops up, everything I tried to do suddenly appears, but then when I exit out of the window, and I disappears again.
