This is a collection of various support items that may address unexpected, undesired, or incorrect behavior, along with some solutions/items to check.
Types of errant behavior:
- Click on key but moves keyboard (or application window) instead of typing
- Moving window will move only in one direction vs. diagonally
- Stuck Shift, Control, or Alt key
In general, restarting your system and testing with a clean/limited tool like Notepad may help identify if the problem is related to the keyboard software or something else in the system. Verifying what can duplicate the problem is an important factor in quickly resolving any operational issues.
Things to check:
- If using macros, ensure macros are keystroke sequences that will work manually
- Touchscreen calibration
- Pen and Touch settings: toggle & test with 'Turn on single finger panning'.
- Other software running in the system
- System speed issues, especially video (visual keyboard painting)
System speed issues with the painting in the software can cause keyboard state issues due to the user/system/typing aspects (i.e. keyboard painting results in delays that affect typing). This is a combination of the system speed, video speed, and the 3D rendering in the software - using the oldest painting method of simple 2D keys can speed painting / eliminate this if the system's video speed / memory is affecting the display (and that is what is causing the keyboard typing/syncing issue).

Notes on keyboard states:
Virtual keystrokes that are interpreted by the system based on the internal keyboard state. There are various ways the system's keyboard state can affected, and could be related to other software in the system, interactions between different types of windows in the system, etc. Sometimes these "incorrect" states can be cleared by pressing the Shift key/Ctrl key once or twice.
If these "incorrect" states occur frequently, it may be worth working with the system to determine what the underlying cause is (or what event/sequence occurs before the problem). Windows also preserves a keyboard state for each open application, and this can be more problematic with windows based command prompt based/DOS type applications due to system speed/interface issues created within Windows.
