if I leaf through my picture collections with the preview window open, the program freezes at some point.
I've already checked all file association settings. Windows board resources are everywhere.
I use Windows 10 and Dopus in the current version.
Please help me that I can finally work properly with DOpus again.
The dump indicates Opus is waiting for the Office+ ActiveX + Preview + Web plugin to close after displaying a previous file (usually a document format like Office or PDF, or a video if the Movie plugin didn't handle the video).
That's probably in turn caused by an issue with another viewer component that isn't part of Opus. The plugin only acts as a proxy for other components so they can work in Opus without being written for Opus.
We'd need to know what the other component is to investigate further. When that plugin is involved, and if the viewer pane is wide enough, it will tell you which component is being use to display the current in brackets next to the file name at the top.
If WMP is freezing, it's often an issue with video codecs/splitters, sometimes triggered by specific files that cause them to crash. Updating or finding alternatives for those components can fix things sometimes.
Have you manually installed any codecs or codec packs?
