I have installed JMRI and I wanted to make a start so that when I get a laptop, I will be able to transfer the files and get things moving.  I have been able to enter the layout editor and create a schematic of my layout, including all the loops and turnouts.  However, when I try to access any table, all that happens is that a hidden blank window is created.  The editor and PanelPro still work at this stage.  However, if I open the window via the PanelPro Window menu item, everything stops working.  I cannot even close PanelPro.  I have to resort to Taskmanager to end the Java Process. I went to the JMRI discussion forum on SouorceForge.net, but I need to register to use that.  I have tried to register with SourceForge, but I get no reply, so I am stuck.  Does anyone have any ideas?

I've not been there for a while, but I used to use the JMRI Yahoo group.

It will be handy if you post  some detail of your PC operating system, version of JMRI you installed and the java version it's running on (from memory I think JMRI has a Help>About box on its main menu that will tell you useful stuff)

Check you have the correct version of JAVA installed.  This is usually what causes problems.

Thanks for the help.  I eventually got some help from JMRI and the issue was a sound file bug in the official release.  I have now installed Test Version 4.11.3 and that has solved the problem.

Yes, I had the same issue, only present in the latest stable release, but as you've found installing the latest test release sorts it!
