I use freemind 0.9 RC1 under ubuntu linux 8.10 with java 1.6.0 and KDE4.1. Freemind runs fine until I edit a long node and simply html loads up. After this keyboard commands are not recognized anymore in the main program. The mouse continues to work. When I edit a long node again, the keyboard works inside simply html, so it seems that keyboard commands get sent to simply html even thought that window is supposed to be closed.
