CLR doesn't do warm start?

[=?Utf-8?B?YmVuamk=?=]

Hi,

As this article (http://msdn2.microsoft.com/en-us/magazine/cc163655.aspx)
mentions, there is a cold and warm start time for managed apps. I'm running a
few .net 2.0 winforms apps on my desktop (XP) and until last week, I had the
expected cold followed by warm time. Now, my cold and "warm" times are about
identical. I don't know what changed. It could be something else that's
running in memory and being a hog, but I'm wondering if there is some CLR
switch that says "disable warm starts" that I can look at?

Thanks...
