I had a file that was working. I exported and imported onto a VM connecting to the initial gateway. When trying to save, I got this error in relation to a numeric entry box. If the box is deleted, it saves normally. This was able to save with this box, previously. Error report: SerializationException: Error during serialization for property 'contentPane' on object '[FPMIWindow]OVERVIEW' caused by SerializationException: Error during serialization for property 'font' on object '[PMINumericTextField]PMINumericTextField[Numeric Text Field]' caused by SerializationException: Unable to create clean copy of class de.javasoft.plaf.synthetica.ScalableFont Ignition v8.1.43 (b2024082010) Java: Azul Systems, Inc. 17.0.11 Do you have any idea what would cause this? The most puzzling part is that it worked fine before being imported in. Thanks in advance! ---

It turned out to be from having what I can only assume was an incompatible font. It was set to the font "Dialog." Changing it to "DialogInput" solved the issue.
