When I pushed reply all the spaces were filled with the little black squares with a question mark in the middle reappeared. They were in my original message. They were empty spaces when I read my e-mail and mysteriously reappeared when I replied. Strange.

Specifically, the line I executed was <@(a.{~?&256)"_1 @ ?&256 ]10 I was very surprised to see output that included a run of 302 chars that is a direct quote from a script I had open (but had not run). I know some pseudorandom generators do things like read system memory, but the vocab says J uses the Mersenne Twister algorithm by default, which I think shouldn't behave like this. Could this be some weird GTK display glitch? I was simultaneously experiencing the bug where it can't properly draw boxes. Has anyone else seen this behavior? Unfortunately it's probably next to impossible to duplicate.
