Excel crashes when I open the file, except.....

[MiNK]

I have a problem that does the following:

Start Excel
Open file 'Order Form' (Order Form is my VBA program)
Excel asks to enable/disable macros
Enable macros
Excel crashes

Now if I do the following:

Start Excel
Open file 'Order Form'
Excel asks to enable/disable macros
Disable macros
Save file (same name/location)
Close file (not Excel)
Open file
Enable macros
Program opens fine.

I suspect that there is some environmental setting that has to be set and
this is initiated by saving.

Anybody have any ideas as I'm losing my mind!!!

Cheers
