rootworld
This problem is intermittent and non reproducible but I have to
ask. Has anyone while using NTuples in root had the problem
that at some point the connection to the data seems to break?
One Draw command works correctly, the next comes up empty
and all subsequent attempts are empty (1d draws have arb. scale
0 to 600 on x axis, -1 to 1 on y axis and zero contents, 2d draws
make a blank canvas). It happens to me maybe 3 or 4 times a
day of continuous ntuple work. Valery captured a whole command
sequence from my history file and we reran it with no failure.
Only solution so far is to .q, root, TFile and proceed - a bit
tedious.
