You win a sticky today!
A couple of days ago after downloading the latest Flash, Firefox and Seamonkey would lose focus upon opening on two different computers. I would have to click somewhere in the browser to use it. No scrolling.
I went to Adobe's site and downloaded the uninstaller and ran it, then deleted the suggested files from Windows/system32.
Went back to Adobe's site and installed Flash again. Same thing happened. Uninstalled again.
This time I went to a site with Seamonkey that uses Flash.
Got the warning message that I was missing a plugin. I clicked on install plugin and it installed from Adobe (?).
After that, both browsers worked perfect.
