I'm new to Vista and haven't "disabled" UAC yet so am in the midst of
enduring all those nagging UAC popup boxes. Yes, I have TweakUAC ready
for that. Recently installed a talking dictionary application dated
from the 16 bit Windows era (1994) and to my surprise there wasn't a
single glitch or pop-up. There are no pop-ups when opening it either
and it actually works better on Vista than XP. Starts instantly on
Vista, takes forever to start on XP as though XP is debating whether
it should let it run. Didn't have to make any compatibility changes,
nothing, worked great "out-of-the-box". Are you telling me that this
program was properly signed from back in 1994? I find that hard to
believe.

Another surprise was a remote control software package from the late
nineties. Vista insisted that the package wasn't compatible with it
all through the installation but gave the option to continue....Bottom
line, it installed properly and now works better on Vista than XP. No
pop-ups, no compatibility adjustments required, nothing.

Wonders never cease.
