As I've written several times: my CP *is* 850, (I hope in general it's a) typical German installation. But I see the empty runcmd()!
Some more info:
System Locale ID: 1031 (de-DE)
Thread Locale ID: 1031 (de-DE)
Default ANSI Code Page: 1252 (ANSI - Lateinisch I)
Active ANSI Code Page: 1252 (ANSI - Lateinisch I)
Default OEM code page: 850 (OEM - Multilingual Lateinisch I)
Active OEM Code Page: 850 (OEM - Multilingual Lateinisch I)
Is DBCS Code Page: No
So, if I see it right, the problem is a bit more complex.
But no idea, what additional info I could supply
(To be sure: tested with fresh - no change.)
