Really I have not done deep tests... My game did compile in previous version, and now it does not compile (just a blank debug windows after pressing F5) if the only SUB I had with comments is folded.
If the SUB with the comments is FOLDed, it does not compile.
it is the same problem with the old version.
Try to put the comment after a command and have the sub folded.
Sorry, I am not at home right now.
