This is all very interesting. Someone claims copyright infringement, because the program's GUI looked too similar? Scary...
Btw, doesn't seem like UltraFXP will always stay freeware. Read here:
To people who bought licenses till now:
1. Your license key still work.
2. You can get email support, freeware users not.
3. You can get access to beta area, freeware users not.
4. Shareware UltraFXP will back in near feature, so keep your license keys.
