Application Sometimes Freezes with the latest WPViewPDF

  • Several users reported me a random freeze of my application at startup. The main window should appear but it is not rendered...
    Madexcept detects that the main thread is frozen and it looks like to be related to WPViewPDF:

    I never experimented this problem before.
    It started when I upgraded to V3.04. Could it be related to:
    << - scroll tracking sometimes froze the viewer (.NET only) >> ?

    Upgrading to V3.05 does not fix the problem.

    Moreover, it is difficult to know what is happening because the problem is random on my machine (1 on 5), while for other customers, it happens more often.

    When I downgraded to a version prior to V3.04, the problem vanished...

    Since I can't debug the WPViewPDF.dll, what can I do? Did someone else experiment this problem?
