Strange bug involving SumatraPDF

[raf]

If I open a PDF in Sumatra from Everything and I try to open another into a new tab, from Windows Explorer, it does not work. Opening a second PDF from Everything is fine.

If I start Sumatra from Windows Explorer, then open a second PDF from Everything, and then a third from Windows Explorer, that works too. If I start Sumatra by itself then I can open PDFs from wherever without a problem.

So, it seems that opening a PDF from Everything stops Sumatra from opening further PDFs from Windows Explorer. I can't imagine why this could be.

This was not a problem with Everything before. With the last update to Everything, this behaviour appeared. I don't know if this is Everything's fault or Sumatra's, but I've also lodged a bug report with SumatraPDF's developer.

I'm using v1.4.1.877 (x64) on a standard Windows 10 installation.

Are Everything / Sumatra running at different privilege levels (say Limited vs Admin, kind of thing)?

No such problem here with Everything x64 1.4.1.899 and SumatraPDF x64 3.2.10766.
Everything service running and Everything itself with normal rights.
I can open any combination of PDFs from Everything, Explorer and Total Commander.
All PDFs are opened in new tabs of the running SumatryPDF.

Please try running Everything as a standard user:

• In Everything, from the Tools menu, click Options.
• Click the General tab on the left.
• Check Everything service.
• Uncheck Run as administrator.
• Click OK.
• Restart Everything (right click the Everything tray icon and click Exit).
