Fade effect (transition effect for menus and tooltips) turns itself on?!?

[Joergen Bech]

I am running XP Professional SP3.

Have a weird problem which has been bugging me for a while:

After my machine has been turned on for a while, the "Fade effect"
suddenly turns itself on and I have to go into Display Properties ->
Appearance -> Effects and turn it off again. Note that the
"Use the following transition effect ..." box has a greyed checkmark
in it rather than a black/white one, which suggests to me that
something is temporarily overriding my off setting rather than
setting it permanently.

My Performance Options -> Visual Effects is set to "Adjust for
best performance" and I have checked (I think) all the related
Registry entries for anything out of the ordinary.

I have pruned the process list with AutoRuns.exe (SysInternals)
and cannot think of anything in the process list that could behave
this way.

No viruses either, as far as I am aware of.

Very, very annoying. Any ideas?

TIA,

Joergen Bech

Never mind.

I noticed that it happens when I start either of two programs
named SaviHost or VSTHost - no matter what plugins I am
using, so I guess it is the host programs themselves which
are affecting this setting. I have switched to another VSTi
host now and the problem has gone away.
