Help to work out why a program no longer runs
There is a bug in Windows notepad.exe which sometimes alters the word-wrapping while you're editing a file. I found several references on the web. To fix this I followed the instructions in
Fix Notepad's CR CR LF bug with a hex editor
and made a copy of notepad and used a hex editor to change just one byte. For several days this ran with no problem but as from yesterday it will no longer run. When I double click on the icon nothing happens, and no window opens. The original unedited notepad opens as normal.
Things that might have changed: windows updates installed - these were mostly for Office 2010 but there was one for 2018-06 Security Monthly Quality Rollup; a full system scan by MalwareBytes, but there doesn't seem to be anything in the scan log to suggest it found a threat.
I would be grateful if someone could suggest things to check that might be stopping this application from running. Grateful for assistance.
