Description of the Issue

Hi. After updating NPP I found out that I can't edit binary files anymore. They open normally, but then if I switch to another file (another tab) and go back, NPP freezes and then shows the binary file stripped from all non-printable symbols.

In the newest version same happens when I open binary via Explorer context menu -> Open in NPP. The only way to view it correctly is to drag it into NPP window.

Steps to Reproduce the Issue

1. open file
2. open another tab
3. go back to the file
