    I've tried to compile with the new force QVGA option, but B4PPC crashes with this error:

    'Attempt to read or write protected memory.' (plus something else that I forgot; my apologies, I didn't write it down and the phone rang.)

    I've tried several times to reproduce the error, but I only get the 'Basic4PPC has encountered an error an needs to close' notice.

    Anyone else encountered this?

    Seems to compile OK for me although I don't have a VGA device to try the exe on. Is it with a particular set of code or does compiling any code, or an empty app, cause it?

    The crash happens with a 60-line app (with no components), and a 20,000-line app. Compiling an empty app works ok.

    The 60-line program - I commented out every line, tried to compile, and it still crashes. I can probably post that one; it's not practical (or possible) for me to post the larger program.

    Post the 60 liner - I'll try it here.

    One 60-line program attached.

    EDIT: I should have mentioned that I removed two controls from Form1, thinking that those might be the problem. It's a label and an arrayList, if I remember correctly.

    Hmmm. So that leaves the question: what's different on my end that causes the crash?

    (Just making sure - you did try to compile it in forced QVGA mode, yes?)

    Thanks for taking the time to check this out.

    Not the first time :( I was too quick and just checked it on the desktop. However it DOES compile fine in ForceQVGA mode.

    Are you running Vista? If so is B4PPC running as an Administrator? If not then might be worth a try as a clutching at straws sort of thing.

    Nope. XP Pro / SP2.

    I'm running Vista on my main machine so I just tried it on my XP Home SP2 laptop. Commented and uncommented, force QVGA compiles no problems.

    Rats. I was actually hoping it would crash for you, too. Since it didn't, it's got to be something specific to my machine. Which means I'll have to tackle this one thing at a time until I have to reformat the drive.

    But thanks again for taking time to look at this.
