Forums Feature Suggestions focus option - script editor

I put the cursor in to the script editor, with the | flashing as if i was ready to type, I ALT + TAB to Firefox and then back to mIRC, the | isn't there to carry on typing with but the script editor is on top, or in focus. But if you do it by using your mouse to go to Firefox and back to mIRC, the | is still flashing ready to type. So it's only a key combo that does it.
