Cannot add a commit message

[Kayla Sanderson]

I am positive I botched something recently as I no longer have the ability to add new commit messages, only select from old ones. This only started happening this afternoon and I don't recall anything odd happening before that. Anyone have a clue what I might have done and how I might undo it? I showed one of my bosses but he hadn't seen this happen in his 12 years here (and they've used SVN for most if not all of those I believe.)

hover your mouse over the horizontal line just below "Recent Messages" button, then drag down. Make sure to resize the dialog vertically to be bit enough.

If that doesn't help, open the settings dialog, go to "saved data", then click the "clear" button for "Dialog sizes and positions".
