I'm having problems with internet connection. I'm using Vista Ultimate 64 and connect to internet via wireless.

I downloaded and installed a program called Real Desktop, and when I tried to run it it bugged out. Firefox was opened in the background. I opened Task Manager and Manually closed Real Desktop only to have another window pop up saying that Firefox stopped working. I restarted firefox and since then no program other then Internet Explorer works online. I uninstalled Real Desktop (though I doubt it was the cause of the problem), nothing changed. I re-installed Firefox, nothing. Then I tried to use Internet Download Manager, and when I tried to resume a file that was on queue it said

An error occurred during download:

...

Details:

Cannot open internet socket.

I tried to use Vista's diagnose and repair option, but it says it can't find any problems...

Anyone know how to help me?

On some forums I've seen people make their avatar so that every time a page loads their avatar changes. Of course it's from preselected group of images. How do I do that? Cause it looks really cool :D

I need a link for free data hoster which will allow me to give a direct link for the file. I don't won't people to wait for like on rapidshare, megaupload, etc. Files are not big, none of them are over 10 MB. Is there such a thing?

Tnx in advance.

I need help on how to determine if the point is in the area enclosed by a circle passing through the three vertices of the triangle, given the coordinates of the point and coordinates of the triangles vertices... Help, someone? I need this soon...
