It used to work so that after you'd saved, if you pressed 'F2' again it wouldn't save unless you'd made changes to the quest file.
Now, you can press F2 as many times as you like to keep saving without changing anything.
Saving in ZQuest
I personally like this better, as it doesn't make people feel that the hotkey stopped working temporarily. 😛
If you're actually worried that this is a bug and needs to be fixed, consider causing a small text box to pop up on trying to save under such conditions which simply states "There's no need to save yet." Or something similar, anyway - If only to provide feedback to the user that their pressing of the F2 key is being acknowledged.
I like having this capability seeing as certain things STILL aren't seen as changes even though they clearly are.
1. Having a dialogue pop up for "Hey stupid, you haven't changed anything" would be the worst thing in the universe.
2. If some things aren't seen as changes, that's a bug.
3. If the File->Save options is disabled, and the Save button (if so configured) is disabled, then why would the keyboard hotkey be enabled? Thus, bug.
The menu was set to disable when it thought a quest was "clean" (already saved) so we could tell when the code that determined when the quest was clean was and was not working properly (this is what brings up the dialog asking you to save when you quit). The F2 key was left intact to that the quest could still be saved in case the code was wrong. Would another kind of visual indicator be better for this? If so, what kind and where should it be placed?
