Stupid Question (Bow usage)

[lhughes41]

Hi,
Great game but am stumbling a bit. My summoner found a bow. It says default is infinite arrows. Yet I can find no way to fire it even after equiping. Using "a" for attack yields nothing. Nor does putting my mouse over a target. I was able to use bows with my ARcher. I did not see any red requirement suggesting I could not use the bow.
What stupid thing am I doing wrong?
Thanks,
p.s. reposted here since found this is the thread for stupid questions

If you are any other class than an Archer, you can purchase the 'Shoot' talent in a Last Hope shop. Last time I checked, it cost 8 Gold.

I think mindslayers and temporal wardens start with it, too.
