Multiple Monitor Software - Specific Issue
 

What's the best way to solve this problem that I'm having in Excel and other programs:

When I go into excel and type ctrl + f, it opens up the find/replace menu on the master/default monitor instead of the window the application is open in.

Which multiple monitor software is the best at correcting this problem? I don't care about the other features like taskbars, etc. I find this is the only annoying thing about using multiple monitors. Software constantly opens additional windows on the wrong monitor and then sometimes locks the window you're working in after it does this.
