Topic: CertificateList - KeyUsageSelect strange behaviour

On a CertificateList I setup a filter to only show certain certificates that must have at least 3 of the uses I need as follows.
.KeyUsageSelect = usageClientAuthentication + usageDataEncipherment + usageServerAuthentication
.StoreLocation = locationLocalMachine
.StoreName = "ROOT"
The problem is that the filter does not seem to work. It filters some certificates out but for example shows a certificate with (Client Authentication,Code Signing,Email Protection,Server Authentication,Time Stamp Signing) - I used your CertInfo VB6 form to get its information. That certificates should not be in the list as it does not have usageDataEncipherment. More strangley if I do a CERT.KeyUsage (usageServerAuthentication + usageClientAuthentication + usageDataEncipherment) method call on that certificate then it returns TRUE.
Am I missing something?
