Bugs you guys need to know about your so-called perfect converter.
Help me by telling me how to fix them please.

There are a bunch of things you can try.

1. Uninstall and reinstall the program.

2. This only seems to occur with you. Look at other's animations on youtube and compare and maybe ask around as well.

3. Make a post on Newgrounds. That's where Swivel first popped up, or was publicized.

Email mike@newgrounds.com for bug reports.

One thing i noticed with swivel ( I don't know if this helps) is that if a symbol is out side the dimensions area too much (your white rectangle area you start with) then it glitches a lot.
