Allegro problems, moving circle leaving trail

Hi,

seeing both the "Light" and "SpaceWars" games, I just HAD to learn Allegro. I've been using the tutorials at Loomsoft.net, and they're great. Everything works fine with the moving circle except it leaves a trail of blue (very common newbie problem I bet). I've used double-buffering and all that and I can definetly notice the difference, but the trail is still there. It doesn't mention anything about this in the tutorial. Any help would be greatly appreciated.

Does anybody have a solution to my problem? This thread is on page 2 already so I thought I'd bump it...

oooo...you're gonna get a nasty post from a mod

Lol, sorry. I just read another tutorial and noticed the clear() function. So I just inserted 'clear(buffer);' before drawing it to the screen. Sorry about that, maybe I should try to fix it by myself a bit more before asking for help.

Yup, and you will learn more that way too.

And yes, clear(buffer) would fix it
