This issue is really curious, it happens also for portable version of MM5 and even if eveything about OS integration is unassociated/unregistered.

BUT: It never happens when MM5 is started from desktop shortcut.
i.e. starting from taskbar shortcut or Windows Explorer exhibits the issue, but starting from desktop shortcut never exhibits the issue.

So far I haven't found what the cause could be, but my suspection is something inside Chromium because Acrobat DC is also using Chromium engine and for each PDF it runs new renderer process.
- if MM5 is already running then there is no issue and Acrobat immediatelly launches new Chromium's renderer process for each PDF that is double-clicked in Windows explorer
- if MM5 is started after the Acrobat then double-clicking PDF causes Acrobat's renderer process to start minute or so (or until MM5 is closed)
- if MM5 is started via desktop shortcut then there is no issue for Acrobat to open the PDF immediatelly

Reason unknown though..

Hmm, further testing shown that it's a bit more strange / complicated:

1) Run Acrobat
2) Run MM from desktop shortcut
3) Run explorer and double-click PDF in explorer
=> no issue

1) Run Acrobat
2) Run MM from taskbar
3) Run explorer and double-click PDF in explorer
=> freeze

1) Run Acrobat
2) Run Explorer
3) Run MM from desktop shortcut
4) Select a PDF in explorer and double-click
=> freeze

1) Run MM5 (no matter how)
2) Run Acrobat
3) Run explorer and double-click PDF in explorer
=> no issue

1) Run MM
2) Run Explorer
3) Run Acrobat
4) Select a PDF in explorer and double-click
=> no issue

So whenever both Acrobat and Windows Explorer are run before MM5 then the freeze happens (no matter which way MM is started).
Whenever Acrobat is started after MM the freeze never happens.
When Acrobat is started before MM5 (but Windows Explorer is closed) then the freeze happens only when MM5 isn't started from Desktop shortcut

This must be something deeper inside the Chromium engine, unfortunatelly recent Chromium update did not help here, assigned to our Chromium expert (Petr) ..
