I'm using the latest version of FL Studio, which is version 19. For the longest time, I had no issues whatsoever.
Now, unfortunately, BB works...but while playing any notes through it, pops and crackles. It's really an unusable product now. No reason it should be doing this though, never happened before.
As far as the problem you two are speaking of, I've never had that issue before. Wish I could be of more help!
I just to know if it is worth purchasing in 2012. My feeling is no, and so I've gone a different route: using Catanya arp to work out bass grooves based on chord progressions and then fine-tuning the output in the piano roll. I never did demo Broomstick properly so I can't say how this compares, but it works where Broomstick just might not, and it isn't worth the risk to try by buying it.
