Error when dragging multiple items from Child pane

[Taxi]

I am consistently getting an error after selecting multiple items in the Child Items pane and attempting to drag them to the Data Explorer pane in order to move them to a new Parent item.

I have tested this with 2 different URD files using both normal and flash drive versions of UR v2.0d with the same results.

The message reads "Error starting drag operation: Access Violation." There is an OK button on the dialog box but it can't be used as the hourglass is busy. However UR is still running in the task manager and not using any CPU resources.

The only solution I have is to end the task and restart UR, which has so far always fixed the problem with no loss of data.
