Robert, I'd be interested to know your reaction to the performance of the

Guthrie's blog posting, there are links there to get both the binary and
source versions.

Other than being slow to load, I find it's performance quite acceptable
for business type apps and by no means would I
call it terrible but then maybe your tolerance "threshold" is lower than
mine, if you get my meaning. ;-)

Nice application, IMHO.
However, simply resize it to see what I mean: It flickers like hell and
the usage of one CPU will be at max. ;-)

Yeah, I was aware of the excessive resize flicker but then all apps do this
more or less to some extent and as for the high CPU usage during resize I
get high CPU usage on resizing all apps so maybe that criticism isn't
applicable. I almost mentioned the resize flicker along with my comment on
slow loading but decided it probably wasn't all that important to most
business app users. BTW, how much time do you spend on resizing your apps
when not looking for flicking .NET apps and I did say your tolerance level
might well be different than mine. ;-)

OTOH the whole flicker thing goes away with Vista and it's new Desktop
Window Manager. :)

"When desktop composition is enabled, individual windows no longer draw
directly to the screen or primary display device as they did in previous
versions of Windows. Instead, their drawing is redirected to off-screen
surfaces in video memory, which are then rendered into a desktop image and
presented on the display."
