Screen resolution changes (often required by games) - should be avoided while using Gramotki. Making such resolution changes may result in displacement of notes on desktop because Gramotki is coded to expect a persistent desktop.
ATM® Deluxe (thank to our PrePress bureau) - if you launch Gramotki at startup, the fonts manged by ATM will not be available in Gramotki's menu and in notes. This is because ATM does activating of fonts in the background. If you ran in this problem try to move your favorite fonts in the System's Font folder.
