Your reply is much appreciated Jon. I will try to be more specific
about the problem in further mails.

I have developed a Java application involving jTree with extensive
drag and drop support, which runs correctly in my Linux box. However,
when I switch to a windows box and access the same Linux box using
cygwin x-server, the drag and drop in jTree stops working.
Interestingly, rest of the application still works fine. After
analyzing a bit I found that x-server is able to recognize the drag
event but fails to recognize a drop event.
Details?
OS : Suse Linux Enterprise Server 10 (i586)
Version : 10
Patch level : 3
Other version information:
Java : JDK 5
Cygwin setup-version: 2.573.2.3
Also tried using Xming 6.9.0.31 ssh same Linux setup from Windows, but
that also doesn't solve the problem.
Is there any setting, which should be done prior to running the Java
swing applications?
Here is a sample code which behaves in exactly same way.

I have no idea how to use that java code to reproduce the problem you are
seeing.
Using the above java code in Linux:
1. Download and Install Java Development Toolkit on your Linux box
(Java sun download site:
http://java.sun.com/javase/downloads/index.jsp), if you do not have it
already.
2. Save the sample code in the above link with the file name
TreeTester.java, say in /home/user/
3. Navigate to TreeTester.java from shell, and compile the java code:
# cd /home/user/
# /usr/java/jdk1.5.0_14/bin/javac TreeTester.java
Ignore any warnings of deprecated APIs.
4. This will create a few .class files in /home/user/ directory. Final
step is to run the Java code, using:
# /usr/java/jdk1.5.0_14/bin/java -classpath . TreeTester
This will open up a GUI, with a jTree each on left and right pane.
You can drag and drop any of the leaf nodes from one jTree to the root
node of the other jTree and this should add a new node in the other
jTree. You will get messages on console for the operations being
performed. Now ssh the same box using cygwin/xming from any other
windows box, and run the application using command in step 4. You
should be able to drag (a small icon will come under cursor indicating
that something is being dragged) but when you will drop it, the new
node would not be added to the tree. Thats where lies my problem!!!
