Ok, short answer for you, Lina:
Look in the TinyMCE directory under assets/plugins. Open the tinymce.functions.php file. Down towards the bottom around line 190 you should see a function that looks like this:
tinyMCE.activeEditor.windowManager.open({
file : cmsURL,
width : screen.width * 0.7, // Your dimensions may differ - toy around with them!
height : screen.height * 0.7,
resizable : "yes",
inline : "yes", // This parameter only has an effect if you use the inlinepopups plugin!
close_previous : "no"
}, {
window : win,
input : field_name
});
Simply change the width and height parameters to whatever you want. Currently they’re set to 70% of the width and height of the user’s screen...but you can always set it to a static value. I figured that a percentage was best but your mileage may vary.
Hope this solves it for you!
