Hi,

after creating your HTML-file be sure to
give the OS some time with DoEvents.

Most of the "problem cases" I came across
are based on frame problems.
I usually track the loading in problemcases
through a eventtracking to a file.
Watch for Navigate2Complete, DownloadComplete
and DocumentComplete and include some indication
of where this document is in the hierarchy
(in case of frames) by URL and/or nesting level.
