I have been seeing this problem since 2.xx releases and I guess it was never resolved.
Or maybe its just me?
When you are working on a project and upload to your FTP site it opens up a process queue, if there is no connection at the moment then all heck beaks loose as the processes keep queueing up. Since I'm on a spotty wifi area, I often loose my internet and don't realize it. So when I get my internet back I am unable to keep working in PHPStorm because I can't upload to my FTP anymore and am forced to quit the application and reopen it.
I can continue to work on my project, but when I say perform a permission change on an FTP folder while I have lost my connection the little diolauge box that has the progress of opening up the actual permissions box stay open and is persistant. So from that point the entire PHPStorm application is unusable! I can access the menus from the top but nothing within PHPStorm.
Has anyone had this issue and found a stable work arount?
