599478
LabVIEW may not update classes on Real-Time targets after changing the inplaceness of a connector pane terminal for a VI within those classes In rare cases, changing the inplaceness of a connector pane terminal for a member VI of a class will not update the class.

601807
Resizing a "Register for Events" Node Crashes LabVIEW When there are at least two "Register For Events" nodes, one inside and one outside of an Event Structure, and the node outside of the event structure is resized, LabVIEW crashes the second time that the node is resized.
602230
Connecting conflicting channel types does not always break the wire Two conflicting channel types should but don't break wire if tunnel is in between on forkable channel wire.
602973
In some cases, using the Min/Max function on array of single precision floating point numbers can cause a VI to fail to compile N/A
603092
Rearranging tabs in tab control can cause a crash When the tabs of a tab control are rearranged, the tab control is corrupted. This causes a crash when saving or running the VI.
603391
Incorrect Out of Memory dialog when using "Active Plot" property node in 64-bit LabVIEW. In 64-bit versions of LabVIEW, calling the active plot property node of a chart generates a popup message indicating three is not enough memory to complete this operation. After clicking on “ok," the VI runs normally.

623269
Attempting to drop a file on a path control in OS X will require the file to be dropped below the path control in some cases When attempting to drop a file on a path control, you must move your mouse below the path control to drop the file rather than dropping the file directly on the control.
