In DVDA 5.2, build 133, has anyone experienced intermittent operation of the external monitor preview on a Windows Secondary Display? I keep having to toggle the external preview button off then on to get the secondary display to preview. Sometimes the external preview icon button is on, but no external preview. Then I click off the button, then on, and preview appears as it should.

Weird, never noticed anything unusual with external preview until this release of DVDA. All other 2 screen operations work fine.
