Memory Leak in arduino IDE

I was teaching a summer camp and a few computers ended up having ~10-12 arduino windows open for about 5 or 6 hours because kids dont know how to close tabs, and even after closing the programs windows gave memory errors, specifically that programs couldnt open because there wasn't enough free memory.

Start by reproducing the report with 10–12 Arduino IDE windows left open for 5–6 hours, then close them and observe whether Windows reports insufficient free memory. Done means the reported memory exhaustion no longer occurs in that scenario; the issue does not name a file, test, or entry point to inspect.
