Thanks for writing.
We've checked on Vista Business and we don't see any anomalies beyond
what IE has.
Please recall that eValid is built "on top of" the IE rendering engine
-- the so-called Trident Renderer. Accordingly, eValid emulates IE
perfectly, for better or for worse.
We know that now and then a page will be presented to IE (or to eValid, which
is the same renderer) that will cause a system failure.
As far as we can tell this kind of failure is NOT due to eValid because
when we see it the error message and traceback information does not point
into the eValid code.
We don't know of any license-checking bug that could cause the phenomena
you are descibing, but thanks for the suggestion. We'll keep it in mind.
