OK, I noticed a similar issue on AST2500 when immediately detecting
resolution after mode change. I added a delay, but it probably needs to
be longer on AST2400... Also, most client's don't handle server-side
resize, so usually the window will close and you'll have to re-open
anyway I think, if the size is changing.
Thanks,
