FCE Ultra GX PROBLEM

i have version 3.2.7 of FCE Ultra GX and when i play duck hunt the zapper doesnt work correctly. i have to hold down B to move the cursor and when i release it to shoot it misses anyway even though im dead on. the game worked fine with a previous version of FCE. please help!

Just download the previous version for now. That's what I did.

That worked thank you!
