RE: lua terminal problem on windows (was gnuplot 4.5 (cvs) windows and cygwin binaries are updated)

[Tatsuro M. <tma...@ya...>]

Hello

Thank you for tests and their report.

Seeing the code modification for lua terminal by Ethan, I cannot find any problem at the moment.

I have tested in the default install directory in C:\Program Files\Gnuplot4.5. At that time, 
************
set term tikz
set out 'test.tikz'
plot sin(x)
set out
*************

I found latex codes in file test.tikz so that I judged that test perhaps went well.  

I cannot find the reason why phenomena that you have found occur at the moment.

It will become late in the night in Japan.  Tomorrow, I'll carry out some trials.

Regards

Tatsuro
