As the title suggests, having "str" in your clipboard causes multiple problems with Picotron.

Pasting "str" into the code editor hard crashes Picotron. It either completely shuts down the program on my pc, or gives a "System error 1".

Trying to open Picotron while having "str" in the clipboard either makes it shut down on boot, or give an "Out of memory" error.

It's relatively easy to avoid once you know about it by just not ever copying "str", but it feels like something that should ideally be fixed.

Thank you!
