Help! Windows Explorer crashes regularly when using "SharePoint" directory synced with OneDrive for Business

Question

We are using SharePoint 2013 and I want to sync document libraries with
OneDrive for Business with my PC running Windows 7.
In general, it works, but my Windows Explorer crashes very often (after a few minutes) when I navigate in the synced directories and open files there (or copy files into them in Windows Explorer).
How can I find out what happens and how to avoid it?
remark:
We are still using Office 2007, so I installed only OneDrive for Business from the Office 2013 DVD and
deactivated all other components like Office 2013 by hand:
(so for example, the shared office feature or MS Info Path etc. were not installed)
Is there a crash log, where I can find more information about the crash?
Does OneDrive maybe need other components to be installed and can I install them without damaging my existing Office 2007 setup?

Answer 1

Did  you check your Event Viewer for any errors during the time when Windows Explorer crashed?
Thanks for this hint!
The Log file says the following, so it seems to be WIDCOMM\Bluetooth Software\btncopy.dll
to be responsible for the crashing Windows Explorer
