I'm working on a JApplet which consists of a JTree component. The JTree needs Drag&Drop supports, and it works fine in my Development IDE(JBuilder). but when i put it in the IE and Drag&Drop a node, it seems that all the CPU resource is allocated to the Applet, I can do nothing but wait for the Drag&Drop operation to end. I can not figure out what happened in the background, Could anyone here can tell me how to solve the question? thanks very much in advance!
