Kerbal Space Program

I've come upon a GUI oddity that, frankly, was confusing the hell out of me.

I've got a space station with a lab on board and several other crew modules that currantly contain science data that I intend to research.

The first time I browse through the (scientific) contents of these modules, I can see the "Process In The Lab" button lit up for every item I haven't already researched, including a display of what the ultimate science payoff will be and (if I roll over the button), how much space it will take up in the lab's research que, and how long it will take to research.

But if I browse through the module's scientific contents a second time, the "Process In The Lab" button is greyed out for most of them, and there is no info available about the stats for researching those items.

Thankfully, if I exit the craft (e.g. to the tracking station) and then return, everything resets back to normal.

It took me a while, but I think I finally figured out what's going on. The system seems to be greying out the items that take up more research points then I have available in my lab. (My lab is currantly using 722 of it's 750 available research points).

It's a great idea, except for two things:

1. Why the inconsistancy? Why is sending the items off to the lab an option on the first browse-through and not any subsequent ones? Either grey out the items that are too much for the lab on every browse-through, or leave the option to research them permanently open (which, I'm guessing means the player would essentially be throwing away the extra science points). When an option is available at first and then inexplicably disappears, it's really confusing!

2. It would be helpful to be told why the option to research the item is greyed-out. A simple rollover dialogue (e.g. "Your lab already has too much research to do!") would make things so much clearer.
