I *think* I've solved the online component of the framework, on Mac+Linux, now.
So, with the fix done, I've uploaded a new version of "On a Space Shooting Trail", which should hopefully work properly, now!
If you've Linux or Mac, be sure to let me know if it does or doesn't work! Be sure to "Enter Your Name" in the options menu.

For Windows folk, I've chopped the "Time until you can shoot again" right the way down to about 1 second. Should be much less frustrating, now.

*phew*
Frantic day, trying to get that all done and recompiled on the different systems, before my Laptop's Battery died!!
