Here I'm dealing with around 50 worksheets each having around 2000 lines
each needs different merging and borders. Its kind of a menu tree. I can't post
the code because of the restrictions otherwise I would already have.
Now you can understand why it is taking 30 minutes to run speed is around 12 to 15 lines per second.
I hope that is not bad the problem occurs only when the excel looses focus and you are somewhat
right that its a windows problem. But i needed to bypass that in excel.
