MicroStation Manager and other file open dialogs look different and more like windows dialogs.
Starting with MicroStation V8 XM Edition...By default most of the file dialogs are using a "Windows" style dialog.This can be disabled in the Preferences:1. From Menubar, go to Workspace > Preferences [Preferences dialog opens]2. Go to the "Look and Feel" category.3. Disable "Use Windows File Open Dialogs".
Note: While using Windows open dialog, it is possible to temporary switch the MicroStation style dialogs, by holding SHIFT and pressing ESC.
