I use the move-line (Alt+Up/Down Arrow) and copy-line (Ctrl+Alt+Up/Down Arrow) key strokes a lot when I develop. When I use these lines in the JSP editor, the screen doesn’t change, and the cursor stops blinking.
I can recover from this by switching to another editor and then back (which seems to force the necessary screen refresh, and the change has taken place), but it is pretty annoying.
On the good side: I’m impressed by how powerful the JSP previewer has become.
