B4J Question B4J generated jar file cannot run from Objects folder.

[Beja]

Hi All,
The compiled jar file opens immediately after compiling in the IDE, and works fine. But when tried open it from the Objects folder, the icon flashes twice but doesn't open..
Any meaning appreciated.

Java version used to create .jar file? OS version used? Java versions installed on computer?
