Version 12.3 x64, build 6183, 5/12/2016.
Recently have had all sorts of hanging issues. I'm running Windows 10 64 bit Pro Insider Preview Build 14986. Can be inconsistent depending on the day as today if I highlight and ini type file it hangs straight away, I use to be able to right click and edit with NotePad++ but won't even get there now. It had for a while would do the same if I double clicked on the desktop or This Computer even a text file so I removed it completley with IOBits Uninstaller and reinstalled, was great for a few days, now have this problem on the ini type files. By the way if I use file explorer no problem at all.
Any ideas would be appreciated as becoming a bit of a piss-off.
