Hi All,
I have a problem with vba code (excel macro) generating many sheets. It
seems to crush at creating 300th sheet.

I'm running it on notebook:
MS Excel 2003
Win XP SP2
1 GB RAM
Intel Pentium 1.73GHz

I've tried to run it also at another notebook:
MS Excel 2003
Win XP SP2
2 GB RAM
Core 2 Duo 2,00GHz
and i got the same error.

It stops at line:
Set NewSheet = oBook.Sheets(1)

Throwing an error:
Run-time error '-2147417848 (80010108)'
Automation error
The object invoked as disconnected from its clients.

If you can give me any hint it would be wonderful. That's not my code, I
have to workout this problem because it worked perfectly as long as it had to
generated about 150 sheets. Since the document grow bigger I had to face this
problem.

The full code:
macro name is GenerateTestScripts
