Uwe,
by window I mean instances, by runs I mean, runs the my Markov-Chain

It would probably be better to adopt the terminology that the things
you are calling "windows" are "sessions".
I open two instances of R, run a million cycle chain in each
instance, and
when they finish, neither window has the object I defined to store
the runs.
I tested this morning and when I open two R windows and run a 5k cycle
chain in each instance, neither window has the object I defined to
store
the runs.
This does not happen when I only have one instance of R open
The most common cause of that behavior is failing to assign the output
of a function to a name. There is an object named ".Last.value" that
hosld the results of the last returned object even it it doesn't have
another name.
lapply(1:10, I)
test <- .Last.value
test
[[1]]
[1] 1
[[2]]
[1] 2
snipped rest of output
But as Uwe said ... without the code, ... and your OS (to answer the
question about memory) .... and your sessionInfo() to make sure that
this is not a GUI-related issue ... we cannot say very much.

Is there a maximum memory allocation for all R windows open?

So you mean you open a million windows at the same time? In that
case we
really need your definition of "window".
.... so... it may be reaching some sort of memory limit
I do not know if any OS / window manager has the capability to open
that
many numbers of windows. But as I said, we need some difintions and
examples.
