Wrong Cursor Position (FengGUI + hovering over widgets)


i use FengGUI with jME 2. I followed one of the tutorials from this page. I added a file called something like JMEFengGUIInputHandler. All widgets are displayed correctly but when i hover with the cursor over a button or something else then the cursor is translated ca. 50 pixels above this button for a very short time. (100 ms maybe)

Then it is translated back to the normal position. This happens only when i leave or enter the area of a input widget… (texteditor, button, etc.)

Has anyone an idea how to solve this problem ?
