I've spent longer than I should on a little tray app that reads source
code from the clipboard and writes it back, syntax highlighted, in HTML
and RTF. Because it's very slow (rendering a mere 44K of source takes ca
a minute on a P90), I decided to implement "delayed rendering". When the
user double clicks on the tray icon, the app parses the source to a
global token list, and puts a NULL on the clipboard in CF_TEXT and "Rich
Text Format". Then, when the user tries to paste plain text, the app
renders HTML; when the user tries to paste rich text, the app renders
RTF.

Thing is, I get a WM_RENDERFORMAT request for the CF_TEXT format as soon
as I call CloseClipboard().

Is this 'by design' and unavoidable? Or is there some way I can force
Windows to delay rendering the CF_TEXT until it's requested, too?

The MSDN CD doesn't seem to say anything about "delayed rendering"
that's not in the SDK help files ....
