I started to test the plugins as you said.
But something told me that the problem is with one of the Npp* plugins.
After remove all and reinstall them one by one, I discovered the cause of the problem, the NppCalc plugin.
This plugin is responsible for evaluating different expressions in Notepad++.
After it is installed, it remains “active” by default.
To turn it off, you have to unmark its “Active Calc” menu option or pressing “Ctrl + Shift + C”.
Reading its description again, it is written:
Evaluate expressions in Notepad++.
...
Q: How does this work?
A: Just type function name and press Enter!
So, if the line has something that can be interpreted as an expression, it evaluates it after you press <ENTER> and shows the result as a new line.
For example, a line without commas and with just the period in the sentence will not be evaluated. Otherwise, it will be read as an expression.
Well,
I can’t remember when and why I installed it, but I think it could be improved by changing the keys to run it or started it inactive after installed.
Thanks for your attention and support.
Cheers!!!
