You are right ot should work. Are you able to post your files here to have a look at?
I don't know why this would happen, maybe because a balloon needs a BoM table to refer too but why not try using a note instead and change the border type to circle. Looks the same as a balloon. Make sure the text is highlighted before applying the border.
I use this for revision traingles when doing a change
Hope this helps
I use "text" in my balloons, too and I'm working out ok. I'm in SW2015 and just upgraded from SW2010 so I would have seen any problems if they existed during that leap.
Make sure the leader of each arrow is actually selecting a component, it might have switched to a ball end and not an arrow and that might be the problem.
I agree with Steve, if you are manually inputting information, then i would not use a balloon due to its relationship to a BOM.
Instead, insert a note with a circular border.
Thanks guys I will use the note method. Makes a lot more sense for what I am wanting to do.
