I had just learned to deal with this problem, but I saw there were some bugs with the same issue fixed on other versions of PMI, so here goes. I have noticed that there has been an “error during serialization…” during the following process:
A text field (either numerical or regular text) is out on a container and fpmi.gui.setTouchscreenModeEnabled(1) has turned on the touchscreen mode. Now, I have PMI in Preview mode, I click on the text field and the touchscreen container pops up. At this point it doesn’t matter if I enter in new text or press cancel, but when I take PMI out of Preview mode without pressing any other buttons (focus is still on the touchscreen container I think) and try to save the project, a serialization error occurs.
Let me know if this doesn’t make sense. Thanks,
