Description

On Windows systems with disconnected mapped network drives, the "Open Project" dialog can take over 30 seconds to appear. The "Open File" dialog does not suffer from this issue.
While attempts to actually access the unavailable network drives can logically lead to timeouts, since the open Project dialog will initially be browsing in folder unrelated to the disconnected drive letters, there is no reason that they should be holding up the initialization of the dialog.

VisualVM snapshot data collected while triggering and waiting for the Open Project dialog is attached.
