|Err...cool down folks!|
Just for info:
Another way to insert a slight delay is to run exe's as a shortcut from "All Programs/Startup" rather than the registry. This also gets delayed further because only registry startups use Prefetch. If you can find the exe for Gmail Notifier it could still be worth a try. In fact the slowest option (marginally) is to put a shortcut from the user group rather than admin, so that it actually goes in:
C:\Documents and settings\<your username>\Start Menu\Programs\Startup
Of course you would "first" have to disable it from the registry but this could be done temporarily by unticking it in msconfig. After bootup you would end up with two entries in msconfig while you are trying it - one ticked, one unticked.
Note that I am assuming Gmail Notifier starts from the registry but I don't really know the program very well.
If it doesn't help, reverse the msconfig ticks then delete the shortcut.
I did once try startup delayer. Sure, it works but for my particular purposes I found myself fiddling around with it forever, gave up and used the above approach instead. Lot of words but actually quite simple to do.
Any chance that with the previous install you had Write Cache enabled on the C drive? It can make a world of difference to preventing startups fighting with each other - but that's another long story LOL.
