Font in Metatrader Library is Huge

 
Somehow the font in MetaTrader library has been changed to about 84 an cant seem to get it back to normal. Where is the setting for this so I can change back to 12 or so? I downloaded another copy into a different directory and now the library in that is huge too.
 
Press Ctrl and roll the wheel of mouse.
 
it seems to be a bug in MT or in chm help file. Text size reacts to setting set in MSIE in view/text size menu option. If it's more than Medium size it will show huge letters. change it back to medium.
 
:-(, I had this problem the same

I modify the 23th line in file metaeditor.xml

.docmenu { width:200px;

change 200px to 20px

After, a friend's tell me can Ctrl + Mouse wheel. faint!
