Illustrator window minimizes itself when opening a new file

[Anna-Ruth22765790k4gw]

When I want to open a second illustrator file the Illustrator window minimized itself and the new file is not able to be opened. I do get an error message each time (attached).

This happens nearly 95% I want to open several illustrator files.

Thanks for your support!

This is a pretty old error. This post covers how to resolve the "not enough room for the window" error.
