Dear Colleagues,
I want to report a problem, which I found today. I installed the latest release of ROOT 5.34/08 and wanted to preview some plots in TBrowser. Unfortunately, when I double-clicked on histogram in the list on the left, in my terminal such a message appeared:
[quote]root [0] TBrowser t
root [1] (class TFile*)0x2218580
Error: Symbol t_vs_phi,EHO is not defined in current scope (tmpfile):1:
Error: Symbol WHI,FULL is not defined in current scope (tmpfile):1:
Error: Failed to evaluate WHI,FULL->Draw()
(const int)0
*** Interpreter error recovered ***[/quote]
The histogram name is “t_vs_phi,EHO-WHI,FULL”. I figured out, that all histograms with a hyphen in their names produce this kind of error. There is no trouble with drawing histograms without a hyphen in their name. Also, their is no trouble with drawing any histograms by executing ROOT macros, so I suspect that this is a TBrowser trouble. In addition to this, it is possible to draw discussed histogram in TBrowser by right-click -> DrawPanel.
My previous ROOT version was 5.34/04 and everything worked properly. I run it on Ubuntu 12.04.
Thank you for any help,
Rafal
