Hi,
when writing PSJR scripts, you often need to use the character "}". On german keyboards, this is accessed by pressing the keys "AltGr"+"0", with "AltGr" being the right Alt key (right besides the space bar). In PI 1.5, this toggles the PI GUI between normal- and full-screen mode (without any resize icons etc in the GUI, similar to "F11" in Internet Explorer and Firefox). Workaround: Copy and paste your "}" characters...
