I *did* not use the install script to run yEd:
java -jar yed.jar
that open JDK is not supported I did not know. sorry for not doing rtfm homework. sInce *anything else* runs just fine under openJDK I was convinced this was a bug and no need to try with official versions.
I can reproduce the behaviour under official Java versions, too.
yEd Info-about says:
"Java Version: 1.6.0_21
Java VM: Java HotSpot(TM) 64-Bit Server VM, Sun Microsystems Inc."
Unfortunately one can not copy and paste this info...
The behaviour reproduces identically under
"Java Version 1.7.0
Java VM: Java HotSpot(TM) 64-Bit Server VM, Oracle Corporation"
yEd is one of my favorite tools for years now.
As this to me occurs a real and important issue I did efforts to report.
Some additional data I forgot and delivered in the way you wantd it by now.
I feel upset and impatient as it feels so long and hard to proove this is really an issue.
This is of course partly because I did not provide you with the required data. For which I am sorry.
I please you to have a look at this so that there can be a fix provided.
I need this tool to run with a proper save as functionality.
