I use KeePass to manage all credentials for my EVE Online accounts. Usernames and passwords are randomly generated and consist of upper and lower case letters and numbers. I have KeePass setup with a global hotkey that I can press to auto fill in and submit the form / log into the game client.
This works just fine with playing EVE natively. However, when I try to log into the clients under ISBoxer, all letters come across as lower case, and I cannot login. Yes I have Key Mappings and Redirection disabled for this. I log into each client one at a time.
It would be really useful if the case of the letters (upper / lower) was preserved. My workaround for this is to manually copy and paste each username and password in. I'm glad I only have 2 accounts now.
