Constant Ticking Sound

[dangerclose]

Hi, my very first post.

I did a preliminary search but didn't find anything.
During a torpedo attack I clicked on the chronometer to take it off the screen and after the torpedo impacted the ticking sound kept going. My torpedo tube indicator light was flashing indicating it was being reloaded. I thought that was why it was still ticking but it kept going even after all the tubes were reloaded.

I just bought the downloaded version w/ uboat missions so everything is up to date as well as my video and sound card drivers.

Has anyone experienced this?

Thanks
