Compiled VB Program Won't Stop Running!?

This is probably a very basic idea in VB programming, but I haven't learned it yet. I complied a VB program I wrote and when I hit the close button, the "X" next to max/min, the prgram appears to end, but if you press ctl-alt-del and see what programs are running it says that the program is still running! If you go to the file menu and hit exit, I have a sub that just calls the end function. If you exit the program this way, it doesnt keep running. So If anyone knows what I'm talking about please help!

Forgot to Unload!!!

Ok I figured it out, for anyone who cares to read this. I wasn't unloading any of my forms. Infact I hadn't been doing this any of the programs I was starting to write. I used to program in Qbasic, GW-Basic and Basica a bunch of years ago, and I didnt know I had to do anything more than just call the end function...oh well I hope someone else learns something from this...

Thanks, very helpful.
