I've only experience one extremely minor issue with Win 7, build 2.2.12 and earlier. I hope I'm not repeating something that has already been addressed.
If, on the side toolbar, you click "Ingredients" to drop down the list and select and ingredient type, say "Yeast" and then open a strain and close it, you can not click on "Yeast" to select another strain unless you first select another ingredient type, say "Grain", then back to "Yeast", or click on "Ingredients" to re-drop the selection list.
I'm certainly no programmer, but this acts exactly like You were selecting "Ingredients" from the top menu bar. This is true for any sidebar selection.
This is not a big deal. It just makes the use of the side tool bar no more convenient than the selections at the top. Which defeats the purpose of having the side bar.
I'm guessing this happens because you are just calling the same functions from side as top.
