Issues Fixed in LabVIEW 2017 SP1 f4 Patch
| ID | Description |
| 659963 | Typecasting from a string to an IVI or VISA IO Control in parallel crashes LabVIEW. |
| 661720 | Tunnels remain on borders of case structures after you drag wired items out of the structure. |
| 673108 | LabVIEW can disconnect wires from tunnels when dragging items between frames of a Flat Sequence Structure. |
| 673910 | Unnecessary tunnels are created when you drag wired items into and out of structures. |
| 677297 | LabVIEW can change the settings of a tunnel when dragging items connected to the tunnel between structures. |
| 679673 | LabVIEW can crash when dragging a node between frames of a Flat Sequence Structure. |
| 680767 | (Windows) In rare cases, LabVIEW can accept ActiveX connections before the ActiveX server has fully initialized. |
| 682179 | LabVIEW can disconnect wires from tunnels when dragging items between structures. |
| 7120211 | LabVIEW can crash when you drag nodes out of a Flat Sequence structure. |
| 713011 | LabVIEW may crash when you drag elements into structures within In Place Element Structures. |
| 714264 | LabVIEW can crash when you drag structures out of a Flat Sequence structure. |
| 715178 | (Windows) Reduced the overhead for drawing images and text on Windows 10. This was most noticeable when there were many different controls with text and/or images to draw. |
| 715347 | Reduced the overhead for updating front panel controls with new data from the block diagram. This was most noticeable for applications with a large number of VIs. |
| 715760 | LabVIEW can crash when you drag items out of nested structures. |
| 716611 | In rare cases, LabVIEW can crash when you place a probe after certain licensed typedefs. |
Issues Fixed in LabVIEW 2017 SP1 f3 Patch
Note: This patch was made available on NI Update Service.
| ID | Description |
| 670440 | When a VI with user events registered leaves memory, there is a potential for the event to still be processed and LabVIEW throws a Null Window error. |
| 674999 | Variants running in parallel have the potential to force execution into a single thread. |
| 681894 | In rare cases, LabVIEW can crash when you access the menu bar if a URL is stored in the clipboard. |
| 686077 | In rare cases, malleable VIs can find their way into an infinite compile. |
| 687146 | Malleable VIs have the potential to store additional debugging data. |
| 687250 | Attempting to use Find Instrument Drivers from the Help menu could fail to connect. |
| 688061 | Nested malleable VIs have the potential to create unintended shared instances of dependencies. |
| 688072 | VI sanity checks sometimes take place additional times. |
| 688094 | Malleable VIs have the potential to start a compile when removed from memory. |
| 688384 | When you apply changes to type definitions, additional compiles may take place. |
| 688992 | In rare cases, a race condition can affect simultaneous remote VI Server open and close calls to the same VI. |
| 691392 | In rare cases, LabVIEW can crash when searching within a VI for text using Find and Replace while VIs are unloaded from memory. |
| 691991 | In rare cases, Type Specialization structures may get out of order until VI is recompiled. |
Issues Fixed in LabVIEW 2017 SP1 f1 Patch
Note: This patch was made available on NI Update Service.
| ID | Description |
| 671753 | The LabVIEW Application Builder has the potential to hang when building malleable VIs with subarray or substring inputs. |
| 672120 | Malleable VIs may not properly break after you rename a class method that the mallable VI calls when performing class substitution. |
| 672133 | Non-required terminals on Malleable VIs fail to revert to their default data type after removing the input of a different data type. |
| 672594 | The LabVIEW Application Builder may incorrectly return error 13 when building a build specification that uses malleable VIs. |
| 673694 | LabVIEW may return old array data from a Call Library Function Node when the error in parameter contains an error. |
| 675386 | LabVIEW has the potential to crash when closing a packed project library containing a child class that references its parent class in its private data control. |
| 676190 | LabVIEW has the potential to crash when loading a VI that has a coercion dot on a class wire when the target class is missing. |
| 677003 | In rare circumstances LabVIEW may hang when you use queue functions with a timeout value of zero. |
| 681475 | LabVIEW has the potential to crash when renaming a VI that calls a preallocated reentrant clone VI if you create a new VI with the old VI's name that calls the same reentrant VI. |
