RE: [ROOT] cannot scroll list: f.ls()

Hi Gail,

This is odd.  In root 3.05/07 I did:

root [0] TFile *f = TFile::Open("Event.new.split9.root");     
Warning in <TClass::TClass>: no dictionary for class Event is available
Warning in <TClass::TClass>: no dictionary for class EventHeader is available
Warning in <TClass::TClass>: no dictionary for class Track is available
root [1] f->ls(); > f_ls.log
root [2] .! cat f_ls.log
TFile**         Event.new.split9.root   TTree benchmark ROOT file
 TFile*         Event.new.split9.root   TTree benchmark ROOT file
  KEY: TProcessID       ProcessID0;1    005b3ee8-3ada-1f42-bfc0-08e8e183beef
  KEY: TH1F     htime;1 Real-Time to write versus time
  KEY: TTree    T;1     An example of a ROOT tree
  KEY: TH1F     hstat;1 Event Histogram

Could you send me your entire output.  By doing:

	root [] TFile f("filename.root")
	root [] f.ls(); > f_ls.log
      root [] .! tail f_ls.log
send me the result so far.
and then
	root [] f.ls();
send me whatever you can still see in the window.

Cheers,
Philippe.

Dear Philippe,

I tried the log file and the file f_ls.log
was created but it was empty.
