2. If possible, try to reproduce the bug on more than one machine.

If the problem persists, then send a bug report to wsr at nih.gov including the following information:

• OS version
• ImageJ version (shown in Help/About ImageJ)
• Java version (shown in Help/About ImageJ)
• Memory assigned to ImageJ (shown in Help/About ImageJ)
• Any error messages
• Steps needed to reproduce the problem (e.g. a macro that exemplifies the problem)
