How to reset Ultraedit's window position

I frequently switch from dual monitor to single monitor and back. Ultraedit 11 will save the last window position and this can be a problem when your last Ultraedit window was opened in a screen that is not there anymore. To reset it, you need to

• open uedit32.INI
• delete the line WindowPos=<series of numbers>
• reopen Ultraedit

Welcome

Hi,
I'm glad you are here and I hope you enjoy it. I'm out of my twenties, live in Europe, work in the computer security area, am a dad of 3 and have to confess that am a geek and have been for a long time. This blog will contain useful tricks, things I learn when trying to subdue my computer to do what I intend it to do and the occasional technology rant. I hope you'll find it useful.
