Crash, exit or high CPU when right-clicking certain files

Opus FAQs

Old known issues:

This information was originally part of the Known Issues list above, but is likely to only be useful to people using very old version of Opus or of the programs that once triggered the problem.

The information has been kept in case it is useful, but moved here to reduce the noise in the main post.

  • Notepad++

    Several people have reported crashes when right-clicking files with older versions of Notepad++ installed. If you have Notepad++ and are experiencing these problems, upgrading to the latest version of Notepad++ may solve them, and is definitely the first thing you should try.

    Newer versions of Notepad++ are not known to cause any problems, but the older version with the problem seems quite widespread for some reason.

  • Bitcasa Cloud Storage:

    This context menu shell extension has triggered problems for several people and is blocked by default in newer versions of Opus. In older versions, you can disable it within Opus by adding the following CLSID to the ignore_context_menus setting:

    {92224F8D-0235-4EBB-BEFB-91AC297C4AEE}

    If you still get crashes when right-clicking drives (as opposed to files and folders) then you may need to use ShellExView to disable the extension system-wide. This may also apply to current versions of Opus.

  • Quick PDF Tools Pro:

    If you have Quick PDF Tools Pro (version 2.1.6.1, as of August 2012) installed you may experience long delays and high CPU usage when right-clicking files in Opus.

    A workaround for the problem was added to Directory Opus 10.1.0.2 and later versions (more detail). Users on older versions of Opus may wish to disable the menu by adding the following CLSID to the ignore_context_menus setting:

    {1A359BC8-317D-462a-AD1C-51022D771581}

    On Opus 10.1.0.2 or above, you can remove the CLSID and you should be able to use Quick PDF Tools again in Opus without problems.

  • Qualcomm Atheros Bluetooth Suite:

    This installs a shell extension which triggered crashes for several people. It is automatically blacklisted by Opus 10.0.2.1 and above. Users on older versions can disable by adding the following CLSID to the ignore_context_menus setting:

    {B8952421-0E55-400B-94A6-FA858FC0A39F}

    (The shell extension appears to create its own background threads and windows when files are right-clicked, then falls over if the extension is unloaded while those threads/windows still exist. The COM object's name, shown in the debug output, is the generic-looking AppShellPage Class, and the associated DLL is C:\Program Files\Bluetooth Suite\BtvAppExt.dll.)

  • CFi ShellToys - Image Resize menu (and possibly other shell extensions that add owner-draw menu items):

    This has been fixed in Opus 10.0.3.3. In older versions, the menu may cause Opus to crash.

    This was not the fault of CFi ShellToys; it just happened to be good at triggering a bug in older versions of Opus.

  • O&O Defrag:

    If you have an old (before May 2009) O&O Defrag installed and you find that Opus exits or crashes when you right-click things, updating to the latest version of O&O Defrag should fix the problem.
