Thank you, Yes, when I change the “Style sheet” setting, I can change font size.
But, I need to Exit from HE, and re-run HE, compile to exe file. Than, HE will accept the new setting value of Style sheet. Otherwise, It’s not working…

Now, I can change the font size of search panel.
But I still can not find the method to change the font size of search box. Please help!

The search box uses the system font so you can’t modify it yourself.
