Oh cool, I'm glad somebody has what it takes to update DSO.
The bug I ran into all the time was, in the text editor, it would randomly quit. I'd say 3 out of 10 times it would save your work as well, which was cool, but the other 7 times... well, it wouldn't save, and it always seemed to be right after writing 2 paragraphs. There was no set way to trigger the bug, either. It would trigger on large files and it would trigger on very small files. Sometimes you could go 20 minutes without it happening, sometimes it would happen every 30 seconds.
//edit: There's another bug where, randomly, it won't open images. A larger (dimensions, or filesize) image of the same file type can be loaded, but randomly, you have an image that won't load. And sometimes it'll load if you tell it again, but you never know.
How to fix it...? I have NO idea. I would suggest an autosave feature. Every X seconds it saves the file. Or maybe a button could be bound to save the file without exiting. Type a few words, save. You know. Like a patch. But it would be great if the problem were solved.
As for contacting DragonMinded, not sure if you guys figured it out but he's something of a recluse. Look on his site for contact information. Anyone seen Gone in 60 Seconds, where the guy told the story about how Shawn Fanning stole Napster's code from him? I think DragonMinded stole the code from somebody, and that's why he gets all ticked off if you suggest a radical new feature like video playback. The guy's a hack, he can't do squat, so rather than say it's outside the scope of his abilities or ask for help, he just shuts down and goes on the offensive. I know it's a pretty crazy theory (and a real mean thing to suggest) but it does support the facts, those I know anyway.
