Thanks for letting me know! Fixed in 1.6.43

Try delay = 1/25 sec

Ah, good to know!

I tried to replicate the situation, but it's working fine here. Not sure why you're getting short file names on your system... File names should look the same in the file system and in the program window.

That combination of parameters is designed to compress the file as much as possible, at the expense of speed. It's much faster when used with default settings: gif2apng Animation.gif

I'm not very familiar with Python, but I would guess you need to change the current working directory with os.chdir() or something like that,

So far, compiling with newer Visual Studio didn't help. Tweaking compiler optimization parameters didn't help either. Maybe AV companies will eventually fix their algorithms. I sent "palse positive" report to one of them.

Thanks for letting me know. It's obviously a false positive. I see only 32-bit version is affected. 64-bit version is fine. I'll see what I can do. Maybe recompiling that 32-bit version will help.
