"OK" button not active (sometimes)

[kengruven]

LimeChat 2.47. Server -> "Add Server...".

• If I fill out "Network name", then "Server", then "Nickname", the OK button becomes active.
• If I fill out "Server", then "Nickname", then "Network name", the OK button stays dimmed (!). But if I tab into and then out of the "Server" field, the OK button activates.
• If I fill out "Nickname", then "Network name", then as soon as I start typing in the "Server" field, the OK button becomes active.

Basically, there's some weirdness with the activation of the "OK" button in this dialog box. It's easy to get into a situation where you've filled out everything you need to, but the "OK" button is still dimmed.
