Can't get zapper to register hits in FCE Ultra GX

Hi! I'm new to Wii emulators and just recently installed FCE Ultra GX v3.1.2. I love the emulator overall, but for some reason I can't get zapper games to work right. I changed my controller in the configuration to zapper and have the cursor on the screen. However, on games like Hogan's Alley and Duck Hunt, I can have the cursor dead on the target, and the shots will not register for some reason. On Hogan's Alley, if the targets are either on the left or right side of the screen, if I pull the trigger enough times, sometimes they will register a hit, other times not. I've rarely been able to hit a target on there in the middle position.

I've also tried the Super Scope 6 support on Snes9x GX v4.1.4 and it works perfectly. I've searched around the net for quite a while for info about this problem with no luck. If anyone has any suggestions or answers, it will be greatly appreciated!!

Already fixed for the next release.

Thanks a ton for taking the time to reply, Tantric! I will check back periodically for the next release of the emulator. Keep up the good work!!
