Hi,
I just tested this on another machine and got no problem:
IDL> !version
{
"ARCH": "x86_64",
"OS": "Win32",
"OS_FAMILY": "Windows",
"OS_NAME": "Microsoft Windows",
"RELEASE": "8.5.1",
"BUILD_DATE": "Nov 14 2015",
"MEMORY_BITS": 64,
"FILE_OFFSET_BITS": 64
}
Either this is a 8.5->8.5.1 issue or the different hardware gives different results (what *I guess* should not happen when using software rendering...).
Cheers,
Helder
