I am using the most current version of DOpus. At start, I can click Word or PowerPoint files and they start correctly. However, after I work for awhile, clicking a filename brings a dialog box that says...
(filename) Not implemented. This problem only seems to happen with MS Office files- doc, docx, ppt, pptx... and it was not a problem until recently (I have been using DOpus forever).
I can right-click on the file and open the file with the "Open with" menu option. (and yes, I have clicked the "open with this every time" option frequently).
If I entirely exit DOpus and restart (or shut down and restart), it temporarily fixes the problem... but after an hour or so, it starts to happen again. I have tried using the "file type" dialog box to fix this, but am not successful with it.
This does not ever happen with Windows Explorer. Even if DOpus is unable to open a file, the Windows file manager has no issues.
DOpus is set to replace Explorer. Changing this setting does not resolve the issue.
