When I make two TTree's write flag true. Both TTrees is written in one file. And the other file is empty.

I added some lines to fix it in ROMEEventLoop.cpp

This is other topic.
Probably, to close TFile after each run is good. 
Because, when program runs for several run, 
 even if program aborts after some runs, files of former runs are safe.
