Xp thinks VB6 app is DOS

Something odd happened to one of my VB6 projects.

Win XP thinks it's an MSDOS program (or a win32 console). No program icon, a different properties window, and when I run the application a black console window appears then disappears without running. If I run under the command window it says "program too big to fit in memory".

I don't think I've changed anything in the project. This program has built and run fine in the past. It will still run OK in the VB6 IDE in debug mode.

How can a VB form based program be interpreted by Windows as something else?

Does this program of your perhaps do any file processing?

Dbl Check your compile options and optimizations... remove all the optimizations, and switch between native and P-code ..

Never saw such a thing happen, Is this the only app that does this or have you saw this happen on that pc from others windows apps?

If only this one then I would do as GremlinSA suggests and double check all the settings for your compile. If still no go I would try to build a new test app and see if the same thing happens. If it does then I would consider re-installing VB.
