Sorry, but I can't reliably duplicate most of these problems observed over the past several days:

• The ide often looses its mind after running for several hours, and then can't be quit or save any recent edits; so it has to be force-quite, and edits are lost unless first cut and pasted elsewhere.

• Similarly the ide appears to get confused about the state of the serial port emulated over usb; seemingly trying to open multiple connections, with most failing. (sometimes fine, sometimes not); and on occasion loosing initial serial data even if attempting to first sync using "while (!Serial){};" ?

• Lastly I'm not sure if it's intentional, but the ide quits if the last open window is closed, which is annoying because if a new file is opened before the current one is closed, any console messages on one, also appears within the other file's console display as well; so it becomes a bit confusing which open file the messages are meant for?
