INSTALLDIR overwritten when moving the DestinationFolder dialog

[tdawson817]

This is odd, when I move the DestinationFolder dialog before changing the destination folder, then I change the installation directory, both folders are written to the dialog on top of each other (picture attached). If I click next, then back, it's cleaned up, and I only get the correct folder. Anybody know how to fix this problem?

Has this dialog been modified from its default events/settings? How are you changing the destination folder (control event, custom action, etc.)?
