texmfstart --file=showcase.pdf --program=context

Dear All I'm using mswincontext and I have an annoying problem which I can't solve. When I hit Show Documentation in the Scite editor Tools menu I get the error message below. pdfopen: mandatory `--file' argument not found.

Exit code: 0

I have tried to sort this out on a few occassions without success, any hints. Keith McKay Hamilton, Scotland -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.344 / Virus Database: 267.10.18/89 - Release Date: 02/09/2005
