Polycrylic finish becoming tacky

I refinished a table about a year and a half ago and used polycrylic to seal the top. Everyone was talking about it and I thought I'd give it a try. Well....the edges of the table are now tacky right where people rest their arms. I'm not happy!
Has anyone else had this problem? It's almost as if the finish has worn away. When Spring gets here, I think I'll sand the top again, stain it, and seal with polyurethane - like I always did before.
Any wisdom?
No pics because there's nothing to see. You just feel it!
