I am running Excel 2007 on Vista (2GB Ram / 3GHz CPU). I am working on an
..xlsm file with 6 short macros and 500 4-column rows of data.

Switching back and forth between the Excel sheet and the VBA code window
takes way too long (about 10 seconds) and saving the workbook also takes
approx 10 seconds. If I use Excel 2000 for the same work, it is extremely
fast - not enough delay to notice.

Nothing wrong with my machine. Anyone know why working on an .xlsm workbook
would on Vista would be so slow? Am I missing something?

Thanks for your help ...

Bill
