I have posted this on OpenGL forum but didnt get much response so I am trying it here. I am keen to use OpenGL with VB6 and the tutorials given on Ne-He site for VB6 are really good. The problem is: When I try to run the Code by pressing "F5" or "Run" the program runs, but when I stop the program, VB6 uses 50% of the CPU usage (I checked it in TaskManager). I have to close VB to free CPU and then do it all again. I am a newbie to OpenGL and i dont know why this is happening. The funny thing is that when I run the exe that is built from the same program and when that is closed, CPU usage drops down to 0% or 1%. Can anyone help me with this. I would like to clarify following things: 1. I am using Intel Dual Core T2300 processor 1.66GHz ASUS laptop. 256MB graphics card, 1GB ram, 80GB harddisk 2. I really want to use VB6 for OpenGL programming for several reasons, and the one is that I love this language and other is that I am lazy to switch back to VC++ or like. Cheers

I am now using Vb.net and the problem is the same.
