My little nephew is 9 he is learning computer programming at his school for very smart kids. He made a computer program the other day and I was genuinely surprised that this little boy is smarter than all of Adobe, Inc. combined! His program did not resize its window unless I did it intentionally. Wow! Maybe I can give you guys his contact info?

Just got back from the organ donation center, ready to pay another Creative Cloud monthly subscription fee. Should cover the cost of fixing this, right?

Please help, every time Illustrator arbitrarily resizes the window on file open it partially obscures the picture of my beautiful family on my desktop and because I have issues with object permanence every time this happens I fear they have all disappeared from this earth and it causes me great distress and mental anguish

This is the only computer application ever made that has this issue. Would be impressive if it wasn't extremely annoying. Please fix

Another horrific issue in addition to the (now again) solved GPU acceleration.

Window size changes when opening files, some panels are closed as a result and the main toolbar is resized...

Please fix that !

Yeah, everyday i have the same problem very annoying. It also refuse to open file.

Please Adobe, this bug is well over a decade old now.
Having to manually resize the window all the time is just so annoying and the occasional error when the window is "too small" to open a file is infuriating.

when i open a file the illustrator window will minimize, not a huge issue but annoying nevertheless

Illustrator has been working this ****** way since the dinosaur age. Not sure who is the genius behind the development team who think this is how it suppose to work.

Same and this is ****!
Any fix?

When opening any files, by clicking on the files themselves on my desktop, the illustrator window shrinks and the popup "The window is too small to open this file" shows. I'm not making the window shrink, it does this automatically. What do I do?
