Well, if the app had virtualization applied to regkeys/files that it laid
down, disabling UAC would be like losing those registry keys/files (I
think). That virtualization is essentially a feature to allow apps that
aren't written for UAC run under UAC and it's disabled if the app marks
itself as being able to handle the truth :). So if you have an app that
isn't written for UAC, it could exhibit these symptoms.

HTH,
