#1589 Can't save files
> What steps will reproduce the problem? Not sure. Trying to save hasn't worked forme on two different occasions. I tried on Linux, and I get an error that goes "java.lang.OutOfMemoryError: Java heap space "ffdec"". I tried on Windows, and I get an error that goes "java.lang.NullPointerException". > What is the expected output? What do you see instead? The file being saved, inestead (see above) > What version of the product are you using? Is it "nightly build"? Which operating system do you have? 11.3.0 Nightly build 1726. > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. Doesn't seem to be file-specific. I just get the same error trying to save any .swf file.
Apologies, forgot to mention. OS's are Linux Mint 20 Cinnamon and Windows 10 2004.
