Mr. Gunther,

I am using the latest and the best (hehehe). Rev. F with 3.1 IDE.
It is not a problem of loosing focus. It happens while I am stepping or walking, especially if I do it
at fast rates. When stepping using Alt-S it happens if I press Alt-S rapidly, with the mouse the same.
Since the FIFO resolves it it sounds to me like a bug with the IDE's serial comms routines.

But I am racking my tiny brains as to how a comms buffering problem could cause such a thing,
except it might be a buffer over-under flow and thus writing in un-allowed memory space and this is causing a 
window close. I.E. the same old story when programming using C/C++ where pointers cause
memory overwrites etc.

I do not know if the IDE is programmed in C or not, but most other programming languages stop
this kind of thing.

Regards

Samuel
