Vista and AutoRedraw

VB6 apps that run fine on XP with a 1G Ram.
but on Vista, the same app, compiled or in IDE fail with a message that it
cannot create the AutoRedraw.
This applies to forms and to pictureboxes with AutoRedraw set true.
If I set it False, the app runs but I can see no pictures.
These are 2 to 4 Meg JPGs getting loaded. Really not a big image.
This generally means there is not enough memory, but why?
The Vista pc has 4G RAM.
Aero is off.
Here do I start?
Is there some work around?

P.S. I see that in System Information of Process Explorer that the Commit
memory was at 2.9G of the Windows Vista 3G possible. (I have 4G but I think
Vista only can use 3G).
So how do I determine what process is using all the RAM?
OK, so this is a VB group, but I am hoping that some of you, like me, are
using VB6 to develop and are running into similar situations and know how to
troubleshoot better than this old codger.
Thanks.

Hi Lorin,

You must be doing something else in your code that is causing a memory leak
or loop. I can use VB6 apps wiht AutoRedraw set to true without this
problem.

This has prompted me to write a memory gauge showing used vs available.

On a Vista PC there is the Reliability and Performance Monitor that is much
easier to use than the XP version.
This app will show what application is causing the problem and much more.
Unfortunately, I rebooted and the problem went away before I discovered the
R&PM app so I never got to see who was eating my memory.
At least now with my own memory monitor app I can easily detect the memory
usage and then use R&PM to see who is eating memory.
This is all more fun than I deserve.
