I'm not seeing any NullPointerException when I open either SWF file in FFDEC 18.0.0. Can you provide more details about the error? You should be able to click the button in the bottom-right corner of the FFDEC window to see the error details, and then you can click a button next to the error to copy it.

Yes, I can't reproduce it too. Please attach the error log of the NullPointerException or specify more what are exact steps to reproduce. I tried open file button and also drag and drop, everything worked for me in "18.0.0". There should be red icon in the lower right corner upon Nullpointer raising as nosamu said.

I got the exception, but not when opening it. I got it while browsing around in the file interface.swf, also it seems to happen randomly and I can never reproduce it consistently. Last time it happened after I opened it and clicked on Images in the tree.

The exceptions should be fixed in nightly 2338. To STA20: The error in ErrorLogFrame is weird, but I added a workaround that may help, try it. I also found and fixed another Nullpointer when fast switching displayed swf/sprites, that might be related. To the OP (DoomTay): Your problem only appeared when the setting "Auto rename identifiers" is on. I strongly discourage against this setting to be on as it may damage the SWF file when you save it. I added a warning when you try to turn it on, so now it seems to be clear what it does.
