The "reopen button" is not available. Regarding #1091, which is about Feather_ePaper_Quotes, found in https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/Feather_ePaper_Quotes and as described in https://learn.adafruit.com/epaper-display-featherwing-quote-display. The "fix" that was merged previously for this changed one fixed-length buffer for a slightly larger one. Instead of fixing the problem, it just postpones it until the new buffer size overflows.
I suggest you also change the strcpy() statement a few lines after the declaration on line 93
static char buff[1024];
. . .
strcpy(buff,str);
to this:
static char buff[512];
. . .
if (strlen(str) >= sizeof(buff)-1) { // protect against buffer overflow
strncpy(buff, str, sizeof(buff)-2);
buff[sizeof(buff)-1] = '\0';
} else {
strcpy(buff,str);
}
That will future proof the code.
Because of the small memory on the microcontroller, I also drop the size of buff back down a bit so you don't have such a large buffer floating around that is empty most of the time.
I'll put together a PR with this fix.
