restart R.app before even attempting to save a history file. This
option had become unchecked while I was trying to find ways to make
the autosave work properly.

GUI without any problems coming up at least during my tests. However,
the automatic loading of history upon exit was still broken: mostly
not working at all, but a couple of times during my tests actually
saving it, once in the corrupted format (with #'s).

After I renamed the history file, the autosave/load seemed to start
working flawlessly as well. All my problems are thus fixed. Thank you!
By the way: since upgrading from 2.5.0 to 2.5.1 I started getting the

startup, either before or after the R splash text. Sometimes it does
not appear at all. Nothing seems broken so far, but I thought I would
