Hi All,

I find that each time after i open a docx file with embedded pptx
file, so long as i click the embedded pptx object, Word 2007 begins to
process the embedded, and at this time, you cann't input any strings
or click any Ribbon tab until Word 2007 finishs processing the
embedded pptx, and any operations during the processing will be
implemented after the handling of embedded pptx, so one question comes
up: any ways to detect that Word 2007 is processing the embedded pptx
object now? or any Word APIs to detect Word is idle now(i.e. no tasks
are processing by Word 2007)?
