hang when running sketch and “transport error 202: bind failed: Permission denied“ in console

[RichardDL99]

Only one Processing session in use. Had stopped the sketch run. Small changes to sketch. Save and run with ^s^r - it locked up. Not sure which did it, I keyed both. No menu items or buttons responding. Alt-space menu appears. Stack dump in console window, but won't text copy.

Hm, could be a bug; a couple ways you might get this:

1. If you managed to hit ctrl-r twice very quickly—where it tried to launch before the code had finished indicating that the first was launching, and basically it kicked off two run threads. (This would be a bug since the code should be indicating immediately that a sketch has started, and not let a second start.)
2. You accidentally hit the “deny” message for the Windows Firewall warning that pops up.
3. Virus scanning software did the equivalent of the previous possibility, preventing the sketch from starting up.
