| Attached program fails 70% of the times on OSX (somewhere inside the do_queued_events stack). Can someone confirm this? | |

| You can't show or hide windows from a thread - only the main thread can do that... | |

| Argh... I missed that. Is this documented somewhere?
Does this include subwindows (I guess so)? | |

| I'm not sure how much documentation we have for the threading support, but essentially anything that hits the display/window system is not allowed outside of the main thread for all versions of WIN32 and OSX and most versions of X11... | |

| We definitively need documentation about threading. I'm unsure whether an entry in each function/method listing the threading status would be better than a list of thread-unsafe functions as an "Appendix C" along with the general rules. Certainly the latter would be easier to do, since 1.1-x is feature-locked anyway.
There are things which may be non obvious:
- Timers are not safe.
- Is changing the label of a top-level window thread safe? Probably not.
- Calling size(), border() etc isn't either.
- What about GL subwindows?
- fl_ask/choice/choose aren't either, along with helper functions that handle their own run() loop. | |
