Hi,
 
I don't know if it occurs to you ever, but once I update ConTeXt to the current release, my pdf file could be opened by Acrobat reader and shows several blank pages. But Foxit reader seems take it pretty well and everything is showed like I imaged. I'm using Windows by the way.
 
Before I gave up Acrobat reader and turned to Foxit reader, I made my last try: I put
\pdfoptionpdfminorversion=3
in my source file and the pdf file shows correctly in Acrobat reader now. When I changed the number to 4, it shows with some problems. When I changed it to 5 and higher, it shows only blank pages.
 
So, just FYI, I suppose the default pdf minor version is 5, and if you have a display problem with your pdf files, try to make it lower.

Sincerely yours,
Chen
