If I try to do a full re-compile, I get the errors mentioned. You twigged my memory so I tried this. (Without success. :( )

In my base.vcx I have a class called _phook. This is the projecthook routine that is executed prior to builds. In the project, it has a space to put this. If this is there, the project will not compile without the error mentioned. (base.vcx is in use.) So I took it out, shut down and restarted the computer.
Went into VFP and confirmd that this was not there. The project compiles, no errors now.

Unfortunately, when I try and run the executable from Windows explorer, I get the Not enough memory errors.
However, if I have VFP 7 open and use the Do from the program menu to run the EXE file, it works no problems.

Have I given more details to aid you in helping me?

A few questions about Thomas asked. I understand the config.fpw, I have a file like that in my poject. I will ocnfirm again that it exists.
I have at least 1.5G free on the HDD and 128M ram. How could I find out if the swap file is not working?

Again, thank you for your help so far...
Mike
