Having a weird problem in 2003 where my popup menus/events disappear!

I click to make an event/edit an event and the popup hides! I have to alt-tab a LOT and click around rpgmaker's selection for the popup to function. Doesn't affect other versions of rpg maker and no idea why. It also occurs when trying to access ANY pop-up: resources, database, etc. Here's video of the problem in action:
