Hi all,

I’m having some problems with Processing 3.5.4 on Mac 10.14.6. I can edit/run/edit/run etc. a sketch a bunch of times (20 or more times) and then this will happen. It finishes executing `setup()`, but doesn’t reach `draw()`. The sketch opens at the size I specified in `settings()` but all I get is a blank grey window. The “java” item in the dock needs to be force quit. The IDE works fine. Every time I do this I get another one of these:

```auto
megacomputer:theapp me$ ps aux | grep [j]ava
me 3403 0.0 0.0 0 0 ?? ?E 2:56pm 0:00.00 (java)
me 3376 0.0 0.0 0 0 ?? ?E 2:54pm 0:00.00 (java)
me 3367 0.0 0.0 0 0 ?? ?E 2:53pm 0:00.00 (java)
me 3304 0.0 0.0 0 0 ?? ?E 2:47pm 0:00.00 (java)
me 3180 0.0 0.0 0 0 ?? ?E 2:37pm 0:00.00 (java)
me 3121 0.0 0.0 0 0 ?? ?E 2:33pm 0:00.00 (java)
me 2523 0.0 0.0 0 0 ?? ?E 1:41pm 0:00.00 (java)

```

These are all unkillable processes. I have to reboot to get the sketch to run, and then it works fine until this happens again. I’m not sure of the cause.

Any ideas what this is?
