Hi
I have an excel workbook with a single worksheet called 'Monitor' .
This contains data which is automatically refreshed about every two
minutes. Now I have written a macro which does the following-

1. Adds a new sheet called Sheet2
2. Copies data from 'Monitor' every fifteen minutes
3. Saves the workbook after copying

In this way, I create a 'history' of the data refreshed (albeit with
wider intervals). This is stock market data by the way.

Now the problem is this. When i run the macro on a static worksheet,
it runs perfectly. Every fifteen minutes. But when i run it on a
worksheet that has the 'Import Data' option enabled, or is a Bloomberg
worksheet (I dunno what they use to refresh data on Bloomberg) , the
scheduling goes haywire. Sometimes it copies data every ten seconds,
sometimes every half an hour.

It almost seems that the Import Data command in excel is somehow
interfering with the scheduling of the macro. I just can't figure out
how. Here is the macro. Please help!

Thanks a million in advance.
Priyanka

Sorry-part of the code got truncated suring copy paste-here is the
full macro
