Do the "artifacts" also include rebooting the computer when in a Win95

Hey folks,
Could one of you nice people please tell me where I can download the
Direct X SDK so I don't have to get it via post from the states??

It's now part of the Platform SDK.. just dl the build environment pack.
It's on the microsoft website.. can't remember their URL :))) 

Anyway...don't forget you only need it to rebuild the DLL, and you'll need
VC++ 5.  Unless of course you want to abandon Allegro altogether an go
full-on DX :)
