it seems TeXstudio has a feature to resize the font size in the editor, if I see correctly:
if you have press CMD and scroll the wheel or on the apple mouse: touch it, it resizes the fonts.
This might be thought of as a work saver, but so far, for me this has a 100% error rate.
(Whenever I used the feature it was by mistake.)
Is there any way to disable this annoying feature?
