I'm currently working on a programme with excel 2003 (communicates with
word...)

Now it has 8 modules and 1 user form (with 576 controls, pretty
big...), totally 161K after exporting.

I noticed that when I open it, run the userform, close userform and
save the excel file...
The size of the excel file can vary from 329K to 427K. (cannot
understand...)

and when the file size is above 400K (approximately), if I run the
program from a button on spreadsheet or from tools menu/Alt+F8, Excel
will crush, need to be closed and want to sent a report to
MS...Heck...But if I open the VBA editor (Alt+F11) then run it (in any
possible ways), most of the times it works perfectly.

So anyone knows what happened? Does it mean that file cannot be larger
that 400K or one form can only have 575 controls? Or there are other
reasons?

Thanks....
